Hello, several Psycopg users report problems with GSS connection attempts, which cause regular crashes on Windows and on macOS in multiprocessing environments. Last report in [1] but looking for `gssencmode` in the bug tracker will bring up other issues whose solution is to add a `gssencmode=disable` to the connection string. Similar errors/solutions can be googled for in other connector libraries (Perl, Ruby).
Psycopg can use the system libpq, but most people rely on the `binary` package to install a libpq in their system and use it without the need of a C compiler on their client. I am considering changing the parameter default to `disable` [2] in the libpq that we ship in the macOS binary packages. I would do the same for Windows but, if I recall correctly, at the moment we don't build a libpq.dll but we use a pre-compiled one. Linux doesn't seem to require such treatment. Would there be any shortcoming in doing so, apart from obviously requiring GSS users to specify prefer/require for the parameter? Thank you very much -- Daniele [1] https://github.com/psycopg/psycopg/issues/1136 [2] https://github.com/postgres/postgres/blob/master/src/interfaces/libpq/fe-connect.c#L136-L141
