Thread: pgsql: Add test case for obsoleting slot with active walsender
Add test case for obsoleting slot with active walsender The code to signal a running walsender when its reserved WAL size grows too large is completely uncovered before this commit; this adds coverage for that case. This test involves sending SIGSTOP to walsender and walreceiver and running a checkpoint while advancing WAL, then sending SIGCONT. There's no precedent for this coding in Perl tests, and my reading of relevant manpages says it's likely to fail on Windows. Because of this, this test is always skipped on that platform.
