| Steps To Reproduce | PostgreSQL version 9.3 Configure the following backend hostnames with streaming replication: backend_hostname0 = 'schoolblocks-prod-lite.zznaok6d92tf.us-west-2.rds.amazonaws.com' backend_hostname1 = 'schoolblocks-prod-lite-read1.zznaok6d92tf.us-west-2.rds.amazonaws.com' The first one is 64 characters long (exactly) and works okay. The second one is 70 characters long and causes the buffer overflow somewhere in the code. Attached is my pgpool.conf file | ||||
