Thanks so much, @Akshat0694

One quick question, is there a reason to remove the autoReconnect=true setting?

[Akshat0694]

Hi there, I removed it because after parsing the _${DATABASEURL}, _${PSQLDATABASE} also contained autoReconnect=true instead of the db name only_. I did not had a chance to modify the the script and it works fine without it (may be not for mysql). I did not find anything relevant while searching for autoReconnect config for postgres. My container has been running for the last 8 days without a problem, though.
