Sorry if this has been covered before, but the mailing list search is
down right now.
What's the best way to check for the existance of a function? I saw
pg_function_is_visible(), but the problem is that I'd need to use
::regprocedure with it, and ::regprocedure generates an error if the
function doesn't exist. Since I can't trap the error in pgplsql that's
no use.
I'm also working on trying to do a select out of pg_proc, but I'm not
having a lot of luck there either...
# select oid,* from pg_proc where proname='user_write_lock_oid' and
proargtypes = ARRAY((SELECT oid FROM pg_type WHERE
typname='oid'))::oidvector;
ERROR: cannot cast type oid[] to oidvector
