Thanks, patch applied.
However, whilst I was testing, I saw just how slow the tool is:
SELECT * FROM pg_attribute
In a PEM database, returns 8150 rows. In pgAdmin 3, this is timed at 676ms
on my laptop. In pgAdmin 4, the busy spinner runs for approx 5 seconds,
then the whole UI freezes. I then have to wait a further 3 minutes and 46
seconds(!!!!) for the operation to complete. Once loaded, scrolling is very
sluggish.
Please make this your top priority - and if you have incremental
improvements, send them as you have them.
