PQconnectPoll will currently block if libpq is compiled with USE_SSL
defined. This restriction may be removed in the future.
</para>
<para>
PQconnectPoll will currently block under Windows, unless libpq is compiled
with WIN32_NON_BLOCKING_CONNECTIONS defined. This code has not yet been
tested under Windows, and so it is currently off by default. This may be
changed in the future.
</para>
<para>
These functions leave the socket in a non-blocking state as if
<function>PQsetnonblocking</function> had been called.
