Is there a better way I'm missing and is "temp" function creation in
Postgres a big performance concern, especially if a server is under load?
The function itself is only one pg_proc row, but if you're expecting
to do this thousands of times a minute you might have to adjust autovacuum
settings to avoid bad bloat in pg_proc.
If you're intending that these functions be use-once, it's fairly unclear
to me why you bother, as opposed to just issuing the underlying SQL
statements.

The intended use is use-once. The reason is that the statements might differ per call, especially when we start doing updates. The ideal would be to just issue the sql statements, but I was trying to cut down on network calls. To batch them together and get output from one query as input for the others (declare variables), I have to wrap them in a function in Postgres. Or am I missing something? In SQL Server TSQL I could declare variables in any statement as required.
