Modified files:
src/backend/access/common: tupdesc.c
src/backend/commands: comment.c
src/backend/optimizer/path: clausesel.c indxpath.c
src/backend/parser: analyze.c
src/backend/utils/adt: formatting.c selfuncs.c
src/include/utils: builtins.h
Added files:
src/include/utils: selfuncs.h
Log message:
Optimizer can now estimate selectivity of IS NULL, IS NOT NULL,
IS TRUE, etc, with some degree of verisimilitude. Split out
selectivity support functions from builtins.h into a new header
file selfuncs.h, so as to reduce the number of header files builtins.h
must depend on. Fix a few missing inclusions exposed thereby.
From Joe Conway, with some kibitzing from Tom Lane.
