When creating or manipulating a cached plan for a transaction control command (particularly ROLLBACK), we must not perform any catalog accesses, since we might be in an aborted transaction. However, plancache.c busily saved or examined the search_path for every cached plan. If we were unlucky enough to do this at a moment where the path's expansion into schema OIDs wasn't already cached, we'd do some catalog accesses; and with some more bad luck such as an ill-timed signal arrival, that could lead to crashes or Assert failures, as exhibited in bug #8095 from Nachiket Vaidya. Fortunately, there's no real need to consider the search path for such commands, so we can just skip the relevant steps when the subject statement is a TransactionStmt. This is somewhat related to bug #5269, though the failure happens during initial cached-plan creation rather than revalidation. This bug has been there since the plan cache was invented, so back-patch to all supported branches.

In most cases, these were just references to the SQL standard in general. In a few cases, a contrast was made between SQL92 and later standards -- those have been kept unchanged.

If an FDW fails to take special measures with a CurrentOfExpr, we will end up trying to execute it as an ordinary qual, which was being treated as a purely internal failure condition. Provide a more user-oriented error message for such cases.

This saves some memory from each index relcache entry. At least on a 64-bit machine, it saves just enough to shrink a typical relcache entry's memory usage from 2k to 1k. That's nice if you have a lot of backends and a lot of indexes.

The initial coding just descended the index if any of the target trigrams were possibly present at the next level down. But actually we can apply trigramsMatchGraph() so as to take advantage of AND requirements when there are some. The input data might contain false positive matches, but that can only result in a false positive result, not false negative, so it's safe to do it this way. Alexander Korotkov

This changes the behavior of the start and stop actions to exit successfully if the server was already started or stopped. This changes the default behavior of the start action: Before, if the server was already running, it would print a message and succeed. Now, that situation will result in an error. When running in idempotent mode, no message is printed and pg_ctl exits successfully. It was considered to just make the idempotent behavior the default and only option, but pg_upgrade needs the old behavior.

The build of .pc (pkg-config) files depends on all makefiles in use, and in dependency tracking mode, the previous coding ended up including /dev/null as a makefile. Apparently, on some platforms the modification time of /dev/null changes sporadically, and so the .pc files would end up being rebuilt every so often. Fix that by changing the makefile code to do without using /dev/null.

Revert the matview-related changes in explain.c's API, as per recent complaint from Robert Haas. The reason for these appears to have been principally some ill-considered choices around having intorel_startup do what ought to be parse-time checking, plus a poor arrangement for passing it the view parsetree it needs to store into pg_rewrite when creating a materialized view. Do the latter by having parse analysis stick a copy into the IntoClause, instead of doing it at runtime. (On the whole, I seriously question the choice to represent CREATE MATERIALIZED VIEW as a variant of SELECT INTO/CREATE TABLE AS, because that means injecting even more complexity into what was already a horrid legacy kluge. However, I didn't go so far as to rethink that choice ... yet.) I also moved several error checks into matview parse analysis, and made the check for external Params in a matview more accurate. In passing, clean things up a bit more around interpretOidsOption(), and fix things so that we can use that to force no-oids for views, sequences, etc, thereby eliminating the need to cons up "oids = false" options when creating them. catversion bump due to change in IntoClause. (I wonder though if we really need readfuncs/outfuncs support for IntoClause anymore.)

This wasn't addressed in the original patch, but it doesn't take very much additional code to cover the case, so let's get it done. Since pg_trgm 1.1 hasn't been released yet, I just changed the definition of what's in it, rather than inventing a 1.2.
