No, what you want to do is not thread safe.

Only 1 thread should access a Pgconn object.

I am not sure if this is the right mailing list I talk to. Please let me
know if I had violated any unwritten rules. :)

I have a global variable PGconn* m_pgconn that is the connection handle
for connecting to the postgresql database. Can I access/use the handle
from multiple threads? Say I have a thread that does some insertion
through this handle/database connection(m_pgconn) and also another
thread that do some insertion *on the same table* through this
handle(m_pgconn), will that break?
