ERROR: CreateTrigger: function.....
Dear list-member,
I'm new to triggers, and want to try them! That's why I generated a function with plpgsql. Creating the function seems to work, as the word CREATE suggest after the CREATE FUNCTION..... statement is being executed!
However when I want to see whether it is really present I type \df myfunctionsname(); within the psql interface, but without a positive result! Any other user-defined function I create which doesn't have an OPAQUE return type, does show up in the list of functions when I issue the \dt-command!
As a result of the failure mentioned above, the CREATE TRIGGER doesn't work either!
Sorry, but I can't figure out what's the problem! Can anybody drop a line how to tackle this problem! By the way I'm currently using PostgreSQL version 7.2.2 on a PC running RedHat 8.0! Thanks in advance!

Certainly does.
However when I want to see whether it is really present I type \df
myfunctionsname(); within the psql interface, but without a positive

Difficult to say what's happening here - especially as you say you're happily
creating other functions. Have you tried "\df abc*" where "abc" is the first
few letters of your function-name?
Perhaps see my (sadly out-of-date) PostgreSQL Notes at:
http://techdocs.postgresql.org/ and see if you can get one of the examples
there to work.
If you're still seeing problems, post the CREATE FUNCTION to the list and
we'll have a look.

AFAIR functions with return type of "opaque" or
"trigger" do not show up when using the \df command.
Try looking directly at the pg_proc system table.

I think it's getting created but \df isn't showing it. At one time \df
deliberately excluded functions that returned OPAQUE. This isn't true
anymore as of 7.3 ...
