pgsql: Partial pgindent of .l and .y files

Partial pgindent of .l and .y files

Trying to clean up the code a bit while we're working on these files
for the reentrant scanner/pure parser patches.  This cleanup only
touches the code sections after the second '%%' in each file, via a
manually-supervised and locally hacked up pgindent.
