From e6daafb8a60b6018f0ded063fa26ba2b3e336b0b Mon Sep 17 00:00:00 2001 From: Rodrigo Ramírez Norambuena Date: Fri, 1 May 2015 13:22:17 -0400 Subject: cdr_pgsql, cel_pgsql: Store maximum buffer size to prevent reallocation The code previously used a fixed size of 512 for the SQL queries. Depending on the size this may require it to grow. This change makes it so if the buffer size does grow the size is stored and next time the buffer will be large enough.
