[Pgpool-committers] pgpool - pgpool-II: Fix SSL connection sometimes hung if lots of data

[User T-ishii]

Log Message:
-----------
Fix SSL connection sometimes hung if lots of data read from backend.
This is caused by the buffering in OpenSSL layer. To fix the problem,
we check the buffer has any pending data by using SSL_pending() before
calling select(2).

See thread [Pgpool-general] Fwd: PGPOOL II 2.3.3 hang in ssl mode for
more details.
