I'm getting this error when I try to debug, only with brake points.
Error: Assertion Failure - PgSQLProtocol.pas, Line 2240

The error happens only when the cursor goes at a pgDac procedure or function.
If we are not on debug mode or if the brake point is after a interaction with pgDac, everything works fine.
Does pgDac comes with debug information?

Enviroment:
Windows 7
Delphi XE2 Update 4
PgDac Standard Edition

If you need more information or a sample code, let me know.

One more information, only running on debug mode (F9) sometimes i'm getting this the same error.
With brake point the error always happens, without I didn't found the situation, but sometimes happens. You click ok on error message, try again and then, no error.

One more database error:
Socket error or Read: WSAgetLastError return 10004 ($2714)

Hi,

When I try to reproduce the problem (including debug and breakpoints), the Assertion Failure does not occur.
Your example code would be useful here. And, please, also specify the protocol (TPgConnection.ProtocolVersion) and the version of PostgreSQL you are using.

Concerning the database error 10004, it may occur when referring to a closed socket.

I found the problem.
In the main form there was a thread executing a select each second to check the server connection.
When I disabled the thread the error does not happen any more.

I found the problem when I tried to migrate the application to Interbase.

Any sugestion to work with PgDac and threads. Do I need a new connection for each thread?

Thank you for attention.

Hi,

Yes, the right way to work in a multithreaded application is to have connection (the TPgConnection) in each thread.
