Tom Lane f0c9397f80 First steps towards statistics on expressional (nee functional) indexes. 
This commit teaches ANALYZE to store such stats in pg_statistic, but
nothing is done yet about teaching the planner to use 'em.
Also, repair longstanding oversight in separate ANALYZE command: it
updated the pg_class.relpages and reltuples counts for the table proper,
but not for indexes.

Bruce Momjian e850e30fc8 Jan: 
someone asked me about the FK deadlock fix, mentioned in the 7.3.3
release notes as 3rd change:

     http://www.postgresql.org/docs/current/static/release-7-3-3.html

Actually, that fix was available with 7.4, not 7.3. Don't know if we can
retroactively change the release-notes though.

A better workaround for the sentence would be something like:

        "and it also happens that the user always has permission"

Looks easier to read, I think.

Tom Lane 391c3811a2 Rename SortMem and VacuumMem to work_mem and maintenance_work_mem. 
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.
