IdoPgsqlConnection::Escape() internally uses PQescapeStringConn() and its documentation states the following: Furthermore, PQescapeStringConn does not generate the single quotes that must surround PostgreSQL string literals; they should be provided in the SQL command that the result is inserted into. So it's intended to use the result in 'string' literals, not in E'string' literals as Icinga did. This results in problems as the behavior of PQescapeStringConn() depends on how the current connection will interpret regular single quoted literals, namely on the value of the standard_conforming_strings variable. The E'string' literals were initially introduced in ac6f3f8acf4f52adedc7908db6452ed6da273ad7 to fix #1206 where PostgreSQL started warning about escape sequences in string literals not supported by the SQL standard (but by PostgreSQL depending on the value of standard_conforming_strings). In the meantime the oldest PostgreSQL version on any platform supported by Icinga increased to 9.2 (CentOS 7) and starting with 9.1, standard_conforming_strings is enabled by default, so there will be no warnings about escape sequences (as the warning is only issued if the escape sequence is actually interpreted by PostgreSQL).

About
Icinga is a monitoring system which checks the availability of your network resources, notifies users of outages, and generates performance data for reporting.
Scalable and extensible, Icinga can monitor large, complex environments across multiple locations.
Icinga 2 is the monitoring server and requires Icinga Web 2 on top in your Icinga Stack. The configuration can be easily managed with either the Icinga Director, config management tools or plain text within the Icinga DSL.
