Can SQLAlchemy cause PostgreSQL connection pool exhaustion?

Question

Python

The situation is simple. SQLAlchemy has executed several tens of thousands of SQL SELECT queries. Then I killed the app. The neighboring application unexpectedly dropped out swearing that the entire pool of slots for the PG was used up.
Could this be related? If yes, how?

Answer 1

try to repeat a strange question
, looking at some pg_stat_activity, and you yourself will understand,
not to mention "killed" - how is it, so that Alchemy did not have time to close the pool?
