I dunno where the cast() queries are coming from, but note that they're
not your SELECT. You are misunderstanding how the code works if you
expect to see query LOG entries from plpgsql queries. For a
non-EXECUTEd plpgsql command, log_statement will only show the query the
first time it is executed in a session, because that log entry is
generated as a side-effect of parsing and planning.
As a means of tracing the execution of plpgsql functions, log_statement
is pretty worthless :-(. I would like us to develop a full-up tracing
and debugging facility for plpgsql, but we haven't got it yet.
