Re: Query to check existence of stored procedure?

If you're on a more recent version, you can try and select the procname
for a proc and trap the error:

decibel=# select 'abs(bigint)'::regprocedure;
 regprocedure
--------------
 abs(bigint)
(1 row)

decibel=# select 'abs(text)'::regprocedure;
ERROR:  function "abs(text)" does not exist
decibel=#

If you don't care about arguments you can use regproc.
