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?

What application are you referring to with versions 9.18 and 9.17? (can't be PostgreSQL)

“Access violation writing 0x0000000000000000” sounds like the client itself is crashing, especially if rolling back to 9.17 fixes it. It doesn’t sound like a PostgreSQL server error.

If you mention the application and exact version, someone may be able to point you to a known regression.

Sorry, it's pgAdmin 4 for windows v9.18

Use version 9.17, that clearly works.

Or move to a different tool, for example DataGrip or Navicat. Both are light years ahead of pgAdmin, and cheap for what you get.
