of Describe on a prepared statement. This was in the original 3.0 protocol proposal, but I took it out for reasons that seemed good at the time. Put it back per yesterday's pghackers discussion.

DestReceiver pointers instead of just CommandDest values. The DestReceiver is made at the point where the destination is selected, rather than deep inside the executor. This cleans up the original kluge implementation of tstoreReceiver.c, and makes it easy to support retrieving results from utility statements inside portals. Thus, you can now do fun things like Bind and Execute a FETCH or EXPLAIN command, and it'll all work as expected (e.g., you can Describe the portal, or use Execute's count parameter to suspend the output partway through). Implementation involves stuffing the utility command's output into a Tuplestore, which would be kind of annoying for huge output sets, but should be quite acceptable for typical uses of utility commands.

the column by table OID and column number, if it's a simple column reference. Along the way, get rid of reskey/reskeyop fields in Resdoms. Turns out that representation was not convenient for either the planner or the executor; we can make the planner deliver exactly what the executor wants with no more effort. initdb forced due to change in stored rule representation.

Both plannable queries and utility commands are now always executed within Portals, which have been revamped so that they can handle the load (they used to be good only for single SELECT queries). Restructure code to push command-completion-tag selection logic out of postgres.c, so that it won't have to be duplicated between simple and extended queries. initdb forced due to addition of a field to Query nodes.

that the types of untyped string-literal constants are deduced (ie, when coerce_type is applied to 'em, that's what the type must be). Remove the ancient hack of storing the input Param-types array as a global variable, and put the info into ParseState instead. This touches a lot of files because of adjustment of routine parameter lists, but it's really not a large patch. Note: PREPARE statement still insists on exact specification of parameter types, but that could easily be relaxed now, if we wanted to do so.

I had inadvertently omitted it while rearranging things to support length-counted incoming messages. Also, change the parser's API back to accepting a 'char *' query string instead of 'StringInfo', as the latter wasn't buying us anything except overhead. (I think when I put it in I had some notion of making the parser API 8-bit-clean, but seeing that flex depends on null-terminated input, that's not really ever gonna happen.)

rewritten and the protocol is changed, but most elog calls are still elog calls. Also, we need to contemplate mechanisms for controlling all this functionality --- eg, how much stuff should appear in the postmaster log? And what API should libpq expose for it?

have length words. COPY OUT reimplemented per new protocol: it doesn't need \. anymore, thank goodness. COPY BINARY to/from frontend works, at least as far as the backend is concerned --- libpq's PQgetline API is not up to snuff, and will have to be replaced with something that is null-safe. libpq uses message length words for performance improvement (no cycles wasted rescanning long messages), but not yet for error recovery.

Add ALTER SEQUENCE to modify min/max/increment/cache/cycle values Also updated create sequence docs to mention NO MINVALUE, & NO MAXVALUE. New Files: doc/src/sgml/ref/alter_sequence.sgml src/test/regress/expected/sequence.out src/test/regress/sql/sequence.sql ALTER SEQUENCE is NOT transactional. It behaves similarly to setval(). It matches the proposed SQL200N spec, as well as Oracle in most ways -- Oracle lacks RESTART WITH for some strange reason. -- Rod Taylor <rbt@rbt.ca>

utility statement (DeclareCursorStmt) with a SELECT query dangling from it, rather than a SELECT query with a few unusual fields in it. Add code to determine whether a planned query can safely be run backwards. If DECLARE CURSOR specifies SCROLL, ensure that the plan can be run backwards by adding a Materialize plan node if it can't. Without SCROLL, you get an error if you try to fetch backwards from a cursor that can't handle it. (There is still some discussion about what the exact behavior should be, but this is necessary infrastructure in any case.) Along the way, make EXPLAIN DECLARE CURSOR work.
