libpq crashing on macOS during connection startup - Mailing list pgsql-general

I have a macOS web server using Postgres that has been very stable until a month or two ago. If I restart the web
serverthe problem seems to go away for a while, but starts happening again within days. I thought it was a PHP issue as
discussedin the link below, but I just noticed in the crash report it seems to be something related to a call from
libpq.

Any ideas or suggestions appreciated.
