Release notes:
http://developer.postgresql.org/pgdocs/postgres/release-8-2-7.html
Remove HIER patch option, since it is not available anymore. The site
is down and original author responses that he does not maintain it
anymore.
PR: ports/116423
Remove option to build and link with thread safety, and always build
thread safe instead. Decided after a discussion with postgresql
hackers, and tested for a while in postgresql83. This helps when
for example linking with openldap, or for using certain programming
languages as postgresql functions.
