Reap the benefits of not having to avoid leaking PGresults.

Remove a bunch of PG_TRY constructs, de-volatilize related
variables, remove some PQclear calls in error paths.
Aside from making the code simpler and shorter, this should
provide some marginal performance gains.

For ease of review, I did not re-indent code within the removed
PG_TRY constructs.  That'll be done in a separate patch.
