Hello,
I had pgadmin logging set to debug which hopefully will help. I have attached the log.
I initially had opened up a query window, wrote a query, ran it, exported it, opened
up the output file in Excel, and then realized that I needed an additional column.
I then closed the spreadsheet but I did not completely close Excel. I modified the query
which required adding another join to get the column. I then ran the query and then
attempted to export the results to a file. Pgadmin went into an infinite loop.
The first query was "SELECT DISTINCT * FROM TABLE"
The second query was "SELECT DISTINCT a.*, b.missing FROM TABLE A INNER JOIN TABLE2 B ON
B.col = A.col"
I have had to force pgadmin to shutdown to kill the race.
I reopened pgadmin, did the above again, and pgadmin again went into a loop.
Perhaps rebooting will fix the issue but the detail in the log file makes me think it won't.
pgadmin 1.6.1, XP SP2, postgres 8.2
