I'm not sure how your DB has an OID of 4 digits. pgAdmin considers all DBs with OIDs less than equal to 16383 as system DBs. So your DB here is considered a system DB.

Hi all,
I've just come across a funny in pgAdmin 4 version 8.13: when I connect from my laptop to a server on the same laptop, not all databases are listed in the tree-view on the left. The server is PostgreSQL 16.6.
Connecting to the server with psql and doing \l shows me 12 databases, including template0 and template1. Likewise, "select * from pg_database" gives me the same 12 rows. However, the treeview shows only 9... template* databases are excluded, plus one other of my own.
Interestingly, when I select from pg_database, the one database of mine which is excluded has an OID of 4; all the others have 5-digit OIDs. I don't know why its OID is so low; it's come forward through a few PG versions over several years, so probably historical baggage.
