ERROR: relation "info" does not exist
A compatibility issue with Craft 3.4.1 and maybe earlier. Running PostgreSQL12+ (PgSQL12+) couldn't finish Craft's installation setup.

I have no idea what change in PgSQL12+ could cause this behavior but downgrading PgSQL12 to lower versions like PostgreSQL11 worked as expected.

However Craft's docs states that PostgreSQL 9.5+ should meet Craft’s server requirements. 

I can't take this for answer to my question because if this is an incompatibility issue than downgrading doesn't answer my question. I believe you guys get to it and crack it as always. 

Anyway here are the logs when tried to run Craft with PgSQL12+.

Update

Running Craft 3.4.6 along with PostgreSQL 12.2 seems to remove the problem. I checked the CHANGELOG-v3 and I couldn't find anything related to PgSQL database.
