@Gerd Wagner: Could you please look into this again? Squirrel 4.2.0 with postgreSql 42.2.20 still doesn't list procedures.
Today, I wrote to an PostgreSQL-Developer on https://github.com/pgjdbc/pgjdbc/issues/950. Maybe this issue will be fixed soon.
That's it! Thank you very much!
Version 3.8.0: No procedures source can be viewed because there is no source tab anymore.
No autocompletion for foreign table names
Autocompletion for foreign tables with ctrl + space
Great news! Thank you!
Version 3.7.1 doesn't show procedures source any more
