is libpq thread safe without configure enable_thread_safety=yes

[andrew klassen <aptklassen(at)yahoo(dot)com>]

I want to use the libpq in a multithreaded process. I intend to use two

different connections for two different threads. The requests and results

for each connection will be handled completely by each thread independently.

I tried to set enable_thread_safety and enable_thread_safety_force to yes.

However, the compile fails because of references to pthread routines which are not

supported by my os. Specifically:

 

../../../src/interfaces/libpq/libpq.so: undefined reference to `pthread_sigmask'
../../../src/interfaces/libpq/libpq.so: undefined reference to `pthread_mutex_unlock'
../../../src/interfaces/libpq/libpq.so: undefined reference to `pthread_mutex_lock'
../../../src/interfaces/libpq/libpq.so: undefined reference to `sigwait'

 

I can change the code to fix this, but I wondering if based on my application it is okay

to just configure without setting enable_thread_safety.

 

Thanks for any help.

Andrew
