pgsql: Post-pgindent cleanup

Post-pgindent cleanup

Make slightly better decisions about indentation than what pgindent
is capable of. Mostly breaking out long function calls into one
line per argument, with a few other minor adjustments.

No functional changes- all whitespace.
pgindent ran cleanly (didn't change anything) after.
Passes all regressions.
