Ok, I will have a look. grep tells me it's called in these places:

./src/backend/postmaster/postmaster.c
./src/bin/initdb/initdb.c
./src/bin/pg_config/pg_config.c
./src/bin/pg_controldata/pg_controldata.c
./src/bin/pg_ctl/pg_ctl.c
./src/bin/pg_dump/pg_dump.c
./src/bin/pg_dump/pg_dumpall.c
./src/bin/pg_dump/pg_restore.c
./src/bin/pg_resetxlog/pg_resetxlog.c
./src/bin/psql/startup.c
./src/bin/scripts/clusterdb.c
./src/bin/scripts/common.c
./src/bin/scripts/createdb.c
./src/bin/scripts/createlang.c
./src/bin/scripts/createuser.c
./src/bin/scripts/dropdb.c
./src/bin/scripts/droplang.c
./src/bin/scripts/dropuser.c
./src/bin/scripts/vacuumdb.c
./src/interfaces/ecpg/preproc/ecpg.c
