The PostgreSQL Global Development Group, specifically these mailing lists, will provide support for "core PostgreSQL", that is the source code you can download from www.postgresql.org and binaries built from that source. The support here does not provide any guarantees, but it also has no well-defined limits. So if you ask well, people will also try to help you with versions that are "out of support" or third-party products like the foreign data wrappers you mention above. Likewise, "the community" has no well-defined limits: in a way, people who provide third-party open source extensions also are a part of the community, or at least the communities overlap. That said, it is a good idea to contact the maintainers of those third-party extensions first: usually, they know more about their product than the general public, and it also keeps mails off the main list that are of little interest to most people.
