Hi,
(sorry for the big mail)
I have 3 applications in windows and they
starts 3 postgres backends.
The 1st app. call the 2nd and this call the 3rd.
In the same place of the 3rd backend, the query freeze.
If I kill the second backend(or app.), the query is released...
Any suggestions?
Thank's
Alexandre
*** This is my ps when the query is freeze:
