You can't just ignore a thrown error like that. What you'd have to do
to make this coding pattern work is to set up a subtransaction, and either

I probably just need to learn the right coding pattern for this.
What is it?
What I want this code to do:
a) If there is a table 'mytable', set theSavedStuff to a pstrdup'd in
TopMemoryContext copy of column s from one row if present.
b) In case of an error because there is no table 'mytable
