After finishing installation Postgres12, I do the following steps. 1.- I enter PSQL and I connect to the base, that is postgres 2.- I create a new database with name test 3.- I connect to the test, to be able to rename postgres 4.- Rename postgres base to company_name 5.- I try to connect with PGADMIN4 and it tells me the wrong password. 6.- There must be some configuration in PGADMIN4. PGADMIN3 connects the renamed base company_name (with errors for not being supported), but accepts the password that PGADMIN4 rejects. 7.- With PSQL it connects perfectly to the renowned base company_name 8.- Any experience with the subject?
