Обсуждение: pgsql and threads don't match

I'm a Linux developer that are making a huge server, and i'm trying out
databases.
Are the postgres librarys not thread-safe?
If not, when will it be?

The Postgres backend is single-threaded software. The client stuff is
probably thread-safe, and both frontend and backend work with thread-safe
libraries. Clients can open multiple connections to backends, so I would
think that you could do so from multiple threads. You might need to take a
mutex on the connection-opening step; not sure about that. Also, there is
a separate process per backend connection, so multiple simultaneous
connections are allowed.

Good luck.

I'm assuming you mean the C libraries?

I can't say about them, but the Java/JDBC is _not_ thread safe - yet. It's
one of the 4 main things to work on once 6.3 is released.
