I have a macOS web server using Postgres that has been very stable until a month or two ago. If I restart the web server the problem seems to go away for a while, but starts happening again within days. I thought it was a PHP issue as discussed in the link below, but I just noticed in the crash report it seems to be something related to a call from libpq. https://github.com/shivammathur/homebrew-php/issues/1862 Any ideas or suggestions appreciated.
