postgres/src/bin/scripts/createuser.c
Magnus Hagander 0301db623d Replace @postgresql.org with @lists.postgresql.org for mailinglists
Commit c0d0e54084 replaced the ones in the documentation, but missed out
on the ones in the code. Replace those as well, but unlike c0d0e54084,
don't backpatch the code changes to avoid breaking translations.
