Standard English uses "may", "can", and "might" in different ways: may - permission, "You may borrow my rake." can - ability, "I can lift that log." might - possibility, "It might rain today." Unfortunately, in conversational English, their use is often mixed, as in, "You may use this variable to do X", when in fact, "can" is a better choice. Similarly, "It may crash" is better stated, "It might crash". Also update two error messages mentioned in the documenation to match.

portable long options. But we have had portable long options for a long time now, so this is obsolete. Now people have added options which *only* work with -X but not as regular long option, so I'm putting a stop to this: -X is deprecated; it still works, but it has been removed from the documentation, and please don't add more of them.

assumed that a sequential page fetch has cost 1.0. This patch doesn't in itself change the system's behavior at all, but it opens the door to people adopting other units of measurement for EXPLAIN costs. Also, if we ever decide it's worth inventing per-tablespace access cost settings, this change provides a workable intellectual framework for that.

Per my recent proposal. I ended up basing the implementation on the existing mechanism for enforcing valid join orders of IN joins --- the rules for valid outer-join orders are somewhat similar.

executing a statement that fires triggers. Formerly this time was included in "Total runtime" but not otherwise accounted for. As a side benefit, we avoid re-opening relations when firing non-deferred AFTER triggers, because the trigger code can re-use the main executor's ResultRelInfo data structure.

a relation's number of blocks, rather than the possibly-obsolete value in pg_class.relpages. Scale the value in pg_class.reltuples correspondingly to arrive at a hopefully more accurate number of rows. When pg_class contains 0/0, estimate a tuple width from the column datatypes and divide that into current file size to estimate number of rows. This improved methodology allows us to jettison the ancient hacks that put bogus default values into pg_class when a table is first created. Also, per a suggestion from Simon, make VACUUM (but not VACUUM FULL or ANALYZE) adjust the value it puts into pg_class.reltuples to try to represent the mean tuple density instead of the minimal density that actually prevails just after VACUUM. These changes alter the plans selected for certain regression tests, so update the expected files accordingly. (I removed join_1.out because it's not clear if it still applies; we can add back any variant versions as they are shown to be needed.)

Make btree index creation and initial validation of foreign-key constraints use maintenance_work_mem rather than work_mem as their memory limit. Add some code to guc.c to allow these variables to be referenced by their old names in SHOW and SET commands, for backwards compatibility.

necessarily following the JOIN syntax to develop the query plan. The old behavior is still available by setting GUC variable JOIN_COLLAPSE_LIMIT to 1. Also create a GUC variable FROM_COLLAPSE_LIMIT to control the similar decision about when to collapse sub-SELECT lists into their parent lists. (This behavior existed already, but the limit was always GEQO_THRESHOLD/2; now it's separately adjustable.)
