Looking very good. The only issues I see are:

- The row headers should auto-size such that they can display the row numbers if the last row was displayed. E.g. if there are 12345 rows in total, then the row header should be sized to display 5 digits.

- The tests are comprehensive, which is awesome. However, every time I ran them, at least one of the feature tests failed. Unfortunately, it was a different one each time. In the last two runs, I got:

Relevant screenshots attached.

- Can you tidy up the regression output a little please? Instead of:

-------

runTest (pgadmin.feature_tests.query_tool_tests.QueryToolFeatureTest)

Query tool feature test ... On demand result set on scrolling...

OK.

On demand result set on grid select all...

OK.

On demand result set on column select all...

OK.

Explain query...

OK.

Explain query with verbose...

OK.

Explain query with costs...

OK.

Explain analyze query...

OK.

Explain analyze query with buffers...

OK.

Explain analyze query with timing...

OK.

Auto commit disabled...

Something like:
