Description: postmaster using 100% cpu from odbc disconnect
Details:
Hi
User connects to database via Visual Basic & ODBC. During his session VB
crashed. The query that was executed was selecting all records from a simple
view (approx 20,000 records). The query has been running for 68 minutes,
postmaster on 100%. If I run the query manually it takes literally
milliseconds to complete.
When I did a netstat -nt I did not see any active connection from the
offending remote user.
Any input would be appreciated.
Thanks

Tried to reproduce this by killing psql mid-query ... no luck.
Do you want to gdb that backend process and see what it's doing?
