Hello,
i'm quite a newbie using postgres 7.2 so this may be an easy question, but how do i add new funtionality? I mean, i
wannaadd a couple of new functions, and i've found this files, pg_proc.h and fmgrtab.c, but i don't know the meaning of
thefields, so i can't add anything.
For instance, in fmgrtab.c:
{ 61, "chareq", 2, true, false, chareq }
i know 61 is like the port or id for the function, "chareq" and chareq the name, but what about the 2, the true and the
false?could be that 2 is the number of arguments?
And in pg_proc.h
DATA(insert OID = 61 ( chareq PGUID 12 f t t t 2 f 16 "18 18" 100 0 0 100 chareq - ))
what's the meaning of those f's?
Thank you very much!
