Problems with timezone

​Hello,

I have the following inconsistency in my environment:

postgres(at)postgres =# SELECT current_timestamp;
now
-------------------------------
*2015-07-27 16:26:40.001694-03*
(1 row)

postgres(at)postgres =# SHOW timezone;
TimeZone
-------------
Brazil/East
(1 row)

postgres(at)postgres =# SELECT blah;
ERROR: column "blah" does not exist

In my log file:

[*2015-07-27 19:27:10.944 GMT*] 3397 <postgres postgres [local] 42703>
ERROR: column "blah" does not exist at character 8
[*2015-07-27 19:27:10.944 GMT*] 3397 <postgres postgres [local] 42703>
STATEMENT: SELECT blah;​

My PostgreSQL version is: 9.2.4

cat /etc/issue
CentOS release 6.3 (Final)
Kernel \r on an \m

Could you help me?

Thanks a lot.

Best regards
