rather than "-" for the "dash" character. Correct SGML markup. Make references to the names of contributors more consistent. Rewrite a bit of prose, and make some other similar cleanups.

> found in a pg_dump archive. It had problems with dollar-quote tags broken across bufferload boundaries (this may explain bug report from Rod Taylor), also with dollar-quote literals of the form $a$a$..., and was also confused about the rules for backslash in double quoted identifiers (ie, they're not special). Also put in placeholder support for E'...' literals --- this will need more work later.

really the source or destination of the archive. I think this will resolve recent complaints that password prompting is broken in pg_restore on Windows. Note that password prompting and reading from stdin is an unworkable combination on Windows ... but that was true anyway.

is certainly no longer immutable, but must indeed be marked volatile. I wonder if it should use the value of now() (that is, transaction start time) so that it could be marked stable. But it's probably not important enough to be worth changing the code for ... indeed, I'm not even going to force an initdb for this catalog change, seeing that we just did one a few hours ago.

in the zic database or zone names found in the date token table. This preserves the old ability to do AT TIME ZONE 'PST' along with the new ability to do AT TIME ZONE 'PST8PDT'. Per gripe from Bricklen Anderson. Also, fix some inconsistencies in usage of TZ_STRLEN_MAX --- the old code had the potential for one-byte buffer overruns, though given alignment considerations it's unlikely there was any real risk.

as per my recent proposal. For now the template data is hard-wired in proclang.c --- this should be replaced later by a new shared system catalog, but we don't want to force initdb during 8.1 beta. This change lets us cleanly load existing dump files even if they contain outright wrong information about a PL's support functions, such as a wrong path to the shared library or a missing validator function. Also, we can revert the recent kluges to make pg_dump dump PL support functions that are stored in pg_catalog. While at it, I removed the code in pg_regress that replaced $libdir with a hardcoded path for temporary installations. This is no longer needed given our support for relocatable installations.

when there are extra resjunk columns in the child node. I found some additional cases involving Append nodes that weren't handled by the prior patch, and it's not clear how to fix them in the same way without breaking inheritance cases. So the prudent path seems to be to narrow the scope of the optimization.

has to recopy the input plan node's targetlist if it removes a SubqueryScan node just below the non-projecting node. For simplicity I made it recopy always. Per bug report from Allan Wang and Michael Fuhr.

on a page, as suggested by ITAGAKI Takahiro. Also, change a few places that were using some other estimates of max-items-per-page to consistently use MaxOffsetNumber. This is conservatively large --- we could have used the new MaxHeapTuplesPerPage macro, or a similar one for index tuples --- but those places are simply declaring a fixed-size buffer and assuming it will work, rather than actively testing for overrun. It seems safer to size these buffers in a way that can't overflow even if the page is corrupt.

a local array isn't guaranteed to have any particular alignment, and so it could slow down the data transfer.

* Merge xmin/xmax/cmin/cmax back into three header fields Before subtransactions, there used to be only three fields needed to store these four values. This was possible because only the current transaction looks at the cmin/cmax values. If the current transaction created and expired the row the fields stored where xmin (same as xmax), cmin, cmax, and if the transaction was expiring a row from a another transaction, the fields stored were xmin (cmin was not needed), xmax, and cmax. Such a system worked because a transaction could only see committed rows from another transaction. However, subtransactions can see rows from outer transactions, and once the subtransaction completes, the outer transaction continues, requiring the storage of all four fields. With subtransactions, an outer transaction can create a row, a subtransaction expire it, and when the subtransaction completes, the outer transaction still has to have proper visibility of the row, for example, for cursors. One possible solution is to create a phantom cid which represents a cmin/cmax pair and is stored in local memory.
