improvement for version after the current one...

From

hello,

pg_admin is creating the SQL for creating / dropping various database objects.

I suggest that the DROP SQL is extended by "IF EXISTS" on objects that support "if exists"

-- DROP TABLE otpflichtfeld;

the SQL in that pane would be

-- DROP TABLE IF EXISTS otpflichtfeld;

best wishes

Harald

Why? If pgAdmin is emitting 'DROP TABLE foo', that is because foo exists.

yes, it does exist. In the database I am connected to. One rather common situation is to have more then one database of the "same" content - staging / production, customer 1 / customer2; version 3 / version 4.

And the obligation to exchange DML from one to the other. Copying the SQL from pgadmin, collecting it in files and mailing them as DB-service-packs to other places ... where the object may or may not exist. Or also developing within the TEST-database with PGADMIN and copying the DML to files to put in RCS.

"DROP IF EXISTS" does work; "DROP" raises an error which has to be dealt with. That dealing is in 90% usage "go on", as the next command usually is to create that object.
