From: Massimo Dal Zotto <dz@cs.unitn.it>

Here is a tar file the new directories, which substitute the old ones
in contrib. Please remove the old directories array, datetime, miscutil,
string and userlock before unpacking the tar file in contrib.

Note that as the modules are now installed in lib/modules I install all
my sql code in lib/sql. In my opinion also the other contributors should
follow these rules.

+These output functions can be used as substitution of the standard text
+output functions to get the value of text fields printed in the format
+used for C strings. This allows the output of queries or the exported
+files to be processed more easily using standard unix filter programs
+like perl or awk.
+
+If you use the standard functions instead you could find a single tuple
+splitted into many lines and the tabs embedded in the values could be
+confused with those used as field delimters.
+
+My function translates all non-printing characters into corresponding
+esacape sequences as defined by the C syntax. All you need to reconstruct
+the exact value in your application is a corresponding unescape function
+like the string_input defined in the source code.
