Tom Lane 40f6524161 Implement constant-expression simplification per Bernard ... Frankpitt, plus some improvements from yours truly. The simplifier depends on the proiscachable field of pg_proc to tell it whether a function is safe to pre-evaluate --- things like nextval() are not, for example. Update pg_proc.h to contain reasonable cacheability information; as of 6.5.* hardly any functions were marked cacheable. I may have erred too far in the other direction; see recent mail to pghackers for more info. This update does not force an initdb, exactly, but you won't see much benefit from the simplifier until you do one.		1999-09-26 02:28:44 +00:00
