Following some links one can find out http://packages.debian.org/source/unstable/postgresql-9.0
http://ftp.de.debian.org/debian/pool/main/p/postgresql-9.0/postgresql-9.0_9.0.1-1.debian.tar.gz
And check that debian package is patching src/include/pg_config_manual.h
and not using the other facility proposed in the comments:
* here's where to twiddle it. You can also override this at runtime* with the postmaster's -k switch.
-#define DEFAULT_PGSOCKET_DIR "/tmp"
+#define DEFAULT_PGSOCKET_DIR "/var/run/postgresql"
But still, I wonder how this -k switch will get a role here, pg_control
certainly won't know about that. I guess it's worse to give a wrong
value rather than none, but that's easy to fix by having a good label
for the line, I guess.
All in all it would be good to have that in pg_control.
