None of those scripts use PostgresNode, which I thought was added in
9.5, but apparently was actually introduced in 9.6. They do all their
own setup/teardown using TestLib.pm routines. TestLib uses a unique
tempdir for each test run, sets it as the unix socket directory, and
disables listening on tcp, so the most obvious conflict is hidden.
The immediate problem appears to be that they all use
tmp_check/postmaster.log . So anything that examines the logs gets
confused by seeing some other postgres instance's logs, or a mixture,
I'll be surprised if there aren't other problems though. Rather than
trying to fix it all up, this seems like a good argument for
backporting the updated suite from 9.6 or pg10, with PostgresNode etc.
I already have a working tree with that done to use src/test/recovery
in 9.5, but haven't updated src/bin/scripts etc yet.
