Removing unnecessary backslashes and whitespace from postgres script.

[bnerickson]

In EL9 (Rocky Linux 9 in my case), awk complains that "escaping" semi-colons is not a known regexp operator:

# /etc/snmp/postgres
awk: cmd. line:26: warning: regexp escape sequence `\:' is not a known regexp operator

It looks like the backslashes are unnecessary. After the change, the script no longer complains:

I also tested this change on an older CentOS Stream 8 deployment (that was not throwing the same warning) and there were no issues after the fact:
