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.
