Note that this change caused breakage on the wiki.postgresql.org infrastructure which still had an old 9.2 psql running. It wasn't Debian's fault that it had not been upgraded yet. But I refuse to buy the argument that I'm doing something wrong here. Shared libraries have SONAMEs to prevent *exactly* this kind of breakage. If you are removing symbols, bump the SONAME.
