postgresql-12

问题 I'm debugging some code that uses SQLAlchemy to interact with a PostgreSQL database. The errors I'm seeing suggest that PostgreSQL is receiving my SQL statements, but perhaps not in the order I intended. So, I thought I'd enable statement logging to see what PostgreSQL is actually getting. I did that a few years ago, using the instructions in How to log PostgreSQL queries? and it worked just fine. (It must have, because I upvoted that question and the accepted answer.) However, that was

问题 Recently, I've started playing around with an old Raspberry Pi 3 b+, and I thought it would be good practice to host a Postgres database on my local network and use it for whatever I want to work through. I understand that running Postgres on a Raspberry Pi with 1GB of memory is not ideal and can take a toll on the SDcard, but I've updated the postgresql.conf file and specified that the data directory path is to utilize a 1TB SSD.

I've tried the following solution and although it does execute, it doesn't have any effect on the array at all: update movies set data = jsonb_set(data, '{actors}',
