PostgreSQL Supported Platforms over Time
The recent discussion about AIX support in PostgreSQL (as of now removed in PostgreSQL 17) led me to look through the project’s history, to learn what platforms we have supported when.
As usual, at some point in the distant past, this was all very murky and hard to decipher from the source code history, so let’s start with … PostgreSQL 6.5 (1999) was the first mention in the source code of support for building on Windows, using MinGW (essentially GCC). This is not a top-level platform in PostgreSQL (it’s covered by the NetBSD template, interestingly enough, even though it’s derived from FreeBSD), but it’s a rare addition of a new operating system nonetheless.
