command strings inserts relative not absolute path of file to process.
This is a side-effect of 2005-07-04 change that makes the server use
relative paths in general. Noted by Bernd Helmle.
deletion code to avoid the case where an upper-level btree page remains "half
dead" for a significant period of time, and to block insertions into a key
range that is in process of being re-assigned to the right sibling of the
deleted page's parent. This prevents the scenario reported by Ed L. wherein
index keys could become out-of-order in the grandparent index level.
Since this is a moderately invasive fix, I'm applying it only to HEAD.
The bug exists back to 7.4, but the back branches will get a different patch.
(blobs) with comments, per bug #2727 from Konstantin Pelepelin.
Mea culpa for not having tested this case.
Back-patch to 8.1; prior branches don't dump blob comments at all.
reference pages documenting that these commands cannot be used within
a transaction block. Also make some minor improvements to the psql
reference page. Patch from Simon Riggs, minor editorialization by
myself.
code relies on the checking macro actually being called at the end, or the
automatic undiversion will produce garbage. These sort of implicit
side-effects undermine the modularity of the macros and happen to break the
ODBC driver which makes use of them.
Also put the warnings at the very end of configure, so there is an even
better chance of seeing them.
node of a SubLink or SubPlan testexpr field. Bug resulted from replacing
the old lefthand/exprs list fields with a simple expression field, and not
remembering that expression_tree_walker is coded to save a few cycles by
recursing directly to self on list fields (on the assumption the walker
isn't interested in List nodes per se). On non-list fields it must of
course call the walker. Possibly that hack isn't worth the risk of more
such bugs, but I'll leave it be for now. Per bug report from James Robinson.
outer joins. Originally it was only looking for overlap of the righthand
side of a left join, but we have to do it on the lefthand side too.
Per example from Jean-Pierre Pelletier.
scenarios. With multiple clinets, only the first client got the right
scaling factor and this gave a illusion of better performance in case
of the scaling factor greater than 1.
