It is not exactly truth... In v3 the query is executed, fetched and all rows are displayed,
No they're not, though they are all transferred to the client which is why it's slower.

We did that in the first beta, and users overwhelmingly said they didn't like or want pagination.
What we have now gives users the interface they want, and presents the data to them quickly - far more quickly than pgAdmin 3 ever did when working with larger resultsets.
If that's pointless for you, then that's fine, but other users appreciate the speed and responsiveness.
