Getting following error in PostgreSQL 9.6.1 DB logs when I tried to view “Scripts=>CREATE Script” on a table in PgAdmin4.1.1 Browser.
PostgreSQL DB has been recently upgraded from version 9.3.9 to 9.6.1 using pg_upgrade utility.
The same browser function worked just fine when pgadmin3 was pointing to PostgreSQL 9.3.9 database (before upgrade).
