To build with Chatbot or AI Topic Summary you need at least pgvector
0.5.1 postgres extension. Yours must be really old - it’s now up to 0.7.0!
First make sure your container is running:
./launcher restart app
then enter your container
./launcher enter app
then go into the database and update the version of pgvector:
:/var/www/discourse# su postgres -c 'psql discourse'
\dx
ALTER EXTENSION vector UPDATE;
\dx
exit
(paste the results of these last commands here).
now leave the container with exit
You should now be able to rebuild.
