FWIW, I made a Pl/PerlU function that did this at one point. At first, I
parsed the postgresql.conf file and rewrote it, but after a while
I switched to the include a writeable file idea. The downside to that was
trying to follow the path of files to figure out what a particular setting
was (e.g. "grep 'effective' postgresql.conf" no longer provided a canonical
answer), so at the end of the day I simply appended a big comment to the bottom
of the postgresql.conf file and added the settings there. Rather than
adding 100 lines for 100 changes to the same variable, the function checked
the postgresql.conf into version control[1] after every change. That might be
ambitious for the SET command to handle, but it would sure be a slick feature :)
If not that, it might be nice to provide a switch to allow 100 lines, with
timestamp, if desired. An optional comment from the command line would be
another nice touch:
SET PERMANENT effective_cache_size='4GB' COMMENT='Added more RAM to box'
[1] As long as your version control was cvs, subversion, git, or rcs.
