Hi,

I recently did major improvements on perfomance on our routines by simply
removing the call for trim functions on specific bottlenecks. Please see
images attached for a simple example.

I'm using PostgreSQL version 9.5.5-1.pgdg80+1 on Debian 8.6. Someone knows
if it's a bug on trim function? Thanks in advance.
