Re: pgAdmin hang on connection drop/reconnect - Mailing list pgadmin-support

Hi,

We also have issues with connections ending abrubtly. Not only with pgAdmin by the way.
We're at the end of a DSL line, and the connection usually has a lot of hiccups.
After one of those hiccups, you have to wait for at least 30 seconds to find out what happened, after which you get a correct error message, and a dialog suggesting to close the server browser.
Sometimes, not quite reproducable, pgAdmin will crash instead of showing the error message.
During these 30 seconds, during which, presumably, pgAdmin waits for a server response, interaction with any of the pgAdmin windows is not possible, so that queries cannot be saved, nor can the request be cancelled.

It seems that the main window in pgAdmin is more sensitive to these hiccups than the SQL window. Sometimes (it's hard to say exactly when, because you can't notice the hiccups otherwise) the main window will not work anymore, whereas the SQL window will.
You can trick pgAdmin to reconnect by pressing the "new" button in the SQL window, the new window will have a connection (copy paste the query and close the stale window).
But it would be MUCH nicer (these hiccups are driving us crazy) if pgAdmin would be less sensitive. For example, reconnect when there is user activity after connection is lost. Also, it would be nice if there would be the option to cancel the query once you notice that the connection has been lost, and the possibility to save your work in those 30-50 secs that sometimes feel like 30 minutes.

Cheers, btw, i am a great pgAdmin fan.

Can you get a backtrace? This might require you to build a debug enabled binary.
