There is a cancel statement, but I presume you want the create index to succeed. You may have to execute the execute() in a background thread to not block  the main thread

Hi,


I use jdbc  to create index on a table, the sql of 'create index' cost about 30 minutes.
Finally I found, the jdbc client thread blocked at PrepareStatement.execute(), not finished.
At server side, query pg_stat_activity, the connection state already be ‘idle’ (index creation finished).

Is there any suggestion? How to deal with the client thread blocking (read for a response message?) and connection leak.


Thanks a lot.
