Procedure calls are not tracked in pg_stat_user_functions / track_functions

Hi all,

It seems that currently procedures do not get tracked when track_functions
is enabled, which means one needs to resort to other workarounds in order
to monitor procedure calls/runtime.

To illustrate:

=# SHOW track_functions;
┌─────────────────┐
│ track_functions │
├─────────────────┤
│ all │
└─────────────────┘
(1 row)

=# CALL abc();
CALL

=# SELECT def();
┌─────┐
│ def │
├─────┤
│ │
└─────┘
(1 row)

=# SELECT * FROM pg_stat_user_functions;
┌─[ RECORD 1 ]────────────────────┐
│ funcid │ 75223 │
│ schemaname │ public │
│ funcname │ def │
│ calls │ 1 │
│ total_time │ 3.222 │
│ self_time │ 3.222 │
└────────────┴────────────────────┘

Was this intentional, or an oversight?

If welcome, I would be happy to work on a patch. Whilst slightly confusing
in terms of naming, we could just track this together with functions, since
one can always join with pg_proc to determine whether something is a
function or a procedure.

Thanks,
Lukas

Yea, that sounds wrong / not ideal to me. I think we should just fix
this, should be easy enough.
