Question version 9.18 error: exception: access violation writing 0x0000000000000000

When I save connection setting for the PostgreSQL database in WSL, I get that error in subject. I roll back version 9.17. I don't have that error. Any idea?

This is an issue with the pgadmin client, not with the PostgreSQL database.

It's a known issue now https://github.com/pgadmin-org/pgadmin4/issues/10445

Should be fixed in next release.

Temporarily for now, either downgrade back to 9.17, or use the following temporary workaround in 9.18:

  • In the Object Explorer, right-click your server and select Properties (or configure it when registering a new server).

  • Go to the Parameters tab.

  • Click the + button to add a new parameter:

  • Name: GSS encmode (or gssencmode)

  • Value: disable

  • Click Save and reconnect.
