Hmm, I'd suggest turning on query logging to make sure pgAdmin is doing what you expect.
Well, I've already done this. I didn't check query log, but a result by selecting rows from modified table.
Anyway I opened a pgAdmin log and didn't find anything special.
I also found something interesting in pgAdmin work. When constraint is defined as "NOT DEFERRABLE", I get "OK" only when I execute whole query at once. PgAdmin probably executes this query using only one statement - it separates each sql command using semicolon delimiter.
If I try to split my query and execute each command separately - I get the same "integrity violation" error as in psql.
I tried also change constraint into "DEFERRABLE". Behaviours of psql and PgAdmin are the same - query executes fine, doesn't matter whether it is executed as single or several statements.
