Failure in GitHub Actions CI

[parsonsmatt]

The persistent-postgresql CI is currently failing with an error message emitted by libpq, probably the underlying C library.

Cf yesodweb/persistent#1197

The error message is here:

Failures:

  src/MigrationTest.hs:41:5: 
  1) Migration is idempotent
       uncaught exception: IOException of type OtherError
       libpq: failed (server closed the connection unexpectedly
       	This probably means the server terminated abnormally
       	before or while processing the request.
       could not send SSL negotiation packet: Success
       )

  To rerun use: --match "/Migration/is idempotent/"

  test/PgIntervalTest.hs:37:5: 
  2) Postgres Interval Property tests Round trips
       uncaught exception: IOException of type OtherError
       libpq: failed (server closed the connection unexpectedly
       	This probably means the server terminated abnormally
       	before or while processing the request.
       could not send SSL negotiation packet: Success
       )
       (after 25 tests)
         15.333255892191s

I have no idea if this is happening for anyone else, but the only results for Googling it are my own tweets complaining about it. Posting here as a pointer to an issue in case anyone else runs across it.

This error is from libpq, and seems to indicate some networking issue. https://git.postgresql.org/gitweb/?p=postgresql.git;a=blob;f=src/interfaces/libpq/fe-connect.c;h=50b5df3490bfa77ef21e3a6aec56ca562b8f3995;hb=refs/heads/master#l2884

It doesn't appear that postgresql-libpq is at fault here. Judging by the fix in yesodweb/persistent#1197, the error seems to surface correctly as an exception.
