Bug #13286: [Stored Configurations] Invalid unicode escaping with PostgreSQL 9.x
https://projects.puppetlabs.com/issues/13286

Hello, 

beginning with PostgreSQL 9.1 the parameter "standard_conforming_strings" will 
have the value "on" as default. 

standard_conforming_strings (boolean)

    This controls whether ordinary string literals ('...') treat backslashes 
literally, as specified in the SQL standard. Beginning in PostgreSQL 9.1, the 
default is on (prior releases defaulted to off). Applications can check this 
parameter to determine how string literals will be processed. The presence of 
this parameter can also be taken as an indication that the escape string syntax 
(E'...') is supported. Escape string syntax (Section 4.1.2.2) should be used if 
an application desires backslashes to be treated as escape characters.

This will throw the following error message:

2012-03-15 11:15:01 CET FEHLER:  ungültiges Unicode-Escape bei Zeichen 184
2012-03-15 11:15:01 CET TIPP:  Unicode-Escapes müssen \uXXXX oder
\UXXXXXXXX sein.
2012-03-15 11:15:01 CET ANWEISUNG:  INSERT INTO "param_values"
("created_at", "line", "resource_id", "updated_at", "value",
"param_name_id") VALUES('2012-03-15 11:15:01.040833', NULL, 154,
'2012-03-15 11:15:01.040833', E'

The following three lines from my .bashrc are responsible for that, because of 
the \u PostgreSQL expects a unicode string.

PS1='${debian_chroot:+($debian_chroot)}\[<%= t_color 
-%>\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]$PS1"

Regards, Dennis
