Re: Content assist / autocomplete hangs the server (latest pgAdmin version) - Mailing list pgadmin-support
Hi,
I would like to echo Cherio's suggestion here. I copy/paste and run very complex scripts every day, and after the recent changes I see the same: "Then it sort of let me do things but everything was like in slow motion: the tree browser, the other SQL tabs - everything became slow as molasses. I logged onto the server and the "pgAdmin4.py" was keeping the CPU quite busy. It didn't recover for some time so I simply restarted the server and switched autocomplete to manual."
When things get really slow I find that I have to close pgadmin completely and re-open it, and if I had let us say 20 tabs open I have to re-create them - painful.
Note that I really LIKE autocomplete to be on when writing NEW scripts, it can be a timesaver. But I cannot turn it off and turn it on again 30 times a day - the scripts I'm running are a mix of existing-run-as-is, existing-modify-run, and new-run. Autocomplete pops up after the semicolon I always put at the end of any script when it's finished, so if you could enable a switch to turn autocomplete off if a semicolon is present it would be helpful... (I generally do NOT want auto-complete when just editing old scripts).
One specific issue I've noticed is that whenever I paste a complex script, I have to wait for the "Loading...." to disappear before executing, or else I get that "ERROR: execute cannot be used while an asynchronous query is underway" message. That's new, but I presume it is doing some kind of script checking and it usually is quick, so that's OK.
NOTE, though, that the hourglass icon to the left of the URL does not change to "this session is idle.." etc, it still says "a command is currently in progress" until you have actually executed something
Best regards

Hi CherioYou can disable the automatic autocomplete option from "File -> Preferences -> Query Tool -> Auto completion -> Autocomplete on key press". We have also fixed an issue to stop autocomplete on arrow keys #7573 which will be available in the next release, meanwhile, you can install the snapshot build.On Wed, Aug 3, 2022 at 11:39 PM Cherio <cherio@gmail.com> wrote:I had to examine certain aspects of a query that looks like this:SELECT COUNT(*)

It didn't recover for some time so I simply restarted the server and switched autocomplete to manual.Not knowing the design I may not be able to make a viable suggestion but maybe some sort of complexity counter (configurable or at least hard-coded at first) should be considered, which would hint to the autocomplete to stop trying, after it realizes the task may be too complex or takes too long to complete.Sure, a query like the one above should probably make use of a temporary table but it is beyond the point - there has to be a safeguard against an overloaded autocomplete. Without such a safeguard an ugly/invalid query or a user error could kill the server for all connected pgadmin clients.--
