that RAND_MAX applies to them, since it doesn't. Instead add a config.h parameter MAX_RANDOM_VALUE. This is currently set at 2^31-1 but could be auto-configured if that ever proves necessary. Also fix some outright bugs like calling srand() where srandom() is appropriate.

rather than the "~~" operator; this made it easy to add ESCAPE features. Implement ILIKE, NOT ILIKE, and the ESCAPE clause for them. afaict this is not MultiByte clean, but lots of other stuff isn't either. Fix up underlying support code for LIKE/NOT LIKE. Things should be faster and does not require internal string copying. Update regression test to add explicit checks for LIKE/NOT LIKE/ILIKE/NOT ILIKE. Remove colon and semi-colon operators as threatened in 7.0. Implement SQL99 COMMIT/AND NO CHAIN. Throw elog(ERROR) on COMMIT/AND CHAIN per spec since we don't yet support it. Implement SQL99 CREATE/DROP SCHEMA as equivalent to CREATE DATABASE. This is only a stopgap or demo since schemas will have another implementation soon. Remove a few unused production rules to get rid of warnings which crept in on the last commit. Fix up tabbing in some places by removing embedded spaces.

Allow this in the parser and in pg_dump, but it is probably not enough for a complete solution. Better to have the feature started then never here.

that giving pg_proc a toast table required solving the same problems we'd have to solve for pg_class --- pg_proc is one of the relations that gets bootstrapped in relcache.c. Solution is to go back at the end of initialization and read in the *real* pg_class row to replace the phony entry created by formrdesc(). This should work as long as there's no need to touch any toasted values during initialization, which seems a reasonable assumption. Although I did not add a toast-table for every single system table with a varlena attribute, I believe that it would work to just do ALTER TABLE pg_class CREATE TOAST TABLE. So anyone who's really intent on having several thousand ACL entries for a rel could do it. NOTE: I didn't force initdb, but you must do one to see the effects of this patch.

Without this, an elog during cache-entry load leaves that catcache unusable. elog in that segment of code is pretty unusual but it can happen.

multiple times in the parsetree (can happen in COALESCE or BETWEEN contexts, for example). This is a pretty grotty solution --- it will do for now, but perhaps we can do better when we redesign querytrees. What we need is a consistent policy about whether querytrees should be considered read-only structures or not ...

- encode 'text' from database encoding to ASCII to_ascii('\256\341k') to_ascii( text, int4 ) - encode 'text' from 'int4' encoding to ASCII to_ascii('\256\341k', 8) to_ascii( text, name ) - encode 'text' from 'name' encoding to ASCII to_ascii('\256\341k', 'LATIN2') Now is supported LATIN1, LATIN2, WIN1250. For other character sets I haven't good resources. Add new encoding is easy... If encoding is not supported returns ERROR. Note --- not exists total corect conversion to ASCII, this function try convert chars those is _probably_ interpret-able in ASCII for others use ' '. But for example for all Czech characters it is sufficient ... hmm Chinese / JAP and other complicated langs have bad luck here :-( Karel

trying to toast tuples inserted into toast tables! Fix is two-pronged: first, ensure all columns of a toast table are marked attstorage='p', and second, alter the target chunk size so that it's less than the threshold for trying to toast a tuple. (Code tried to do that but the expression was wrong.) A few cosmetic cleanups in tuptoaster too. NOTE: initdb forced due to change in toaster chunk-size.

on myself to do something about the non-self-consistency of the inet comparison functions. The results are probably still semantically wrong (inet and cidr should have different comparison semantics, I think) but at least the boolean operators now agree with each other and with the sort order of indexes on inet/cidr.

These two routines will now ALWAYS elog() on failure, whether you ask for a lock or not. If you really want to get a NULL return on failure, call the new routines heap_open_nofail()/heap_openr_nofail(). By my count there are only about three places that actually want that behavior. There were rather more than three places that were missing the check they needed to make under the old convention :-(.

result, in fact nearly the opposite of what it should, because it was passing the not-equal operator to eqsel() which would use it to compare the value against the most common value in the column, and of course obtain the wrong result therefrom. Must pass the equality operator to eqsel() instead. Fortunately that's easy to get from the oprnegate link.

At this point I think it'd be possible to make float4 be pass-by-value without too much work --- and float8 too on machines where Datum is 8 bytes. Something to try when the mood strikes, anyway.

- Added code to dump 'Create Schema' statement (pg_dump) - Don't bother to disable/enable triggers if we don't have a superuser (pg_restore) - Cleaned up code for reconnecting to database. - Force a reconnect as superuser before enabling/disabling triggers. - Added & Removed --throttle (pg_dump) - Fixed minor bug in language dumping code: expbuffres were not being reset. - Fixed version number initialization in _allocAH (pg_backup_archiver.c) - Added second connection when restoring BLOBs to allow temp. table to survive (db reconnection causes temp tables to be lost).

allows fixing problems with operators that expected to be able to return a NULL, such as the '#' line-segment-intersection operator that tried to return NULL when the two segments don't intersect. (See, eg, bug report from 1-Nov-99 on pghackers.) Fix some other bugs in passing, such as backwards comparison in path_distance().

I did not force. I marked numeric as compressable-but-not-move-off-able, partly to test that storage mode and partly because I've got doubts that numerics are large enough to need external storage.

the planner may try to generate them as a result of transitivity of the existing int2-vs-int4 and int4-vs-int8 operators. In fact, it is now necessary that mergejoinable cross-datatype operators form closed sets. Add an opr_sanity regress test to detect missing operators.

FreeBSD/Intel and DecUX/Alpha machines. The bug appears in postgresql 6.5.3 and 7.0.2. Can someone please review it and apply it to the source tree? Sometimes when the postgres connection dies it is necessary to attempt to reconnect. Calling the pgconnection::Connect method in a derived class leaks memory because it does not clear the current connection (if there is one). These patches ensures that any open connections are closed before attempting to open a new one. -Michael Richards
