Обсуждение: function delete problems

I have made some functions which I wish to remove or remake. These are
'returns opaque' functions that are used for triggers.

I cannot remove them using the drop function <name> command.

obf=> drop function trgpeoplehidden;
ERROR:  parser: parse error at or near ";"

Quoting the function name doesn't seem to help.

What is the best ways of listing, deleting and  updating functions?

(Also, is there a way of seeing what function a trigger on a table
calls? I've tried \d <triggername>).

Thanks for any help
Rory

fred=# \h drop function
Command:     DROP FUNCTION
Description: Removes a user-defined C function
Syntax:
DROP FUNCTION name ( [ type [, ...] ] )
                   ^                  ^
                    Don't omit these!

fred=# drop function bla;
ERROR:  parser: parse error at or near ";"
fred=# drop function bla();
ERROR:  RemoveFunction: function 'bla()' does not exist

.. which is correct.

Rory,

Warning: You're about to feel really dumb.  Don't worry, it's happened to me,
too.

That's
DROP FUNCTION trgpeoplehidden();
the parens are mandatory.

You also need to drop the trigger, manually ... dropping the function does not
automatically drop the trigger, though it does break the trigger.
