Description: memory leak with libpg.dll
Details:
1) DB server is down.
2) the client will connect to these DB server and is running correctly in a
timeout. the problem is: for each connection attempt that will fail the
memory usage is growing. that will result in massive memory allocation, if
the client try to reconnect in high frequency. and furthermore the memory is
not freed when the next connection can be established.
3) I guess in libpg.dll are some connection structures that are not freed
correctly if the connection coult not established well.
