[Pgpool-committers] pgpool - pgpool-II: Fix find_primary_node() so that it judges primary

[User Kitagawa]

Log Message:
-----------
Fix find_primary_node() so that it judges primary node correctly.

Remove pgpool_walrecrunning() from find_primary_node() and
add find_primary_node_repeatedly() that waits until finding primary node.

The reason for removing pgpool_walrecrunning() is that 
"pg_is_in_recovery() AND pgpool_walrecrunning()" cannot judge 
primary node and standby node correctly.
