Import PostgreSQL 9.0 data types support modules as databases/postgresql90-datatypes

This package provides the following PostgreSQL modules:
  - citext
  - hstore
  - intarray
  - isn
  - ltree
  - lo
  - uuid-ossp
  - unaccent

The "citext" module provides a case-insensitive character string type,
citext. Essentially, it internally calls lower when comparing values.
Otherwise, it behaves almost exactly like text.

The "hstore" module implements the "hstore" data type for \ 
storing sets
of key/value pairs within a single PostgreSQL value. This can be useful
in various scenarios, such as rows with many attributes that are rarely
examined, or semi-structured data. Keys and values are simply text strings.

The "intarray" module provides a number of useful functions and operators
for manipulating one-dimensional arrays of integers. There is also support
for indexed searches using some of the operators.

The "isn" module provides data types for the following international
product numbering standards: EAN13, UPC, ISBN (books), ISMN (music),
and ISSN (serials). Numbers are validated on input, and correctly
hyphenated on output.

The "ltree" module implements a data type ltree for representing
labels of data stored in a hierarchical tree-like structure.
Extensive facilities for searching through label trees are provided.

The "lo" module provides support for managing Large Objects (also called
LOs or BLOBs). This includes a data type "lo" and a trigger \ 
"lo_manage."

The "uuid-ossp" module provides functions to generate universally unique
identifiers (UUIDs) using one of several standard algorithms. There are
also functions to produce certain special UUID constants.

"unaccent" is a text search dictionary that removes accents (diacritic \ 
signs)
from lexemes. It's a filtering dictionary, which means its output is always
passed to the next dictionary (if any), unlike the normal behavior of
dictionaries. This allows accent-insensitive processing for full text search.
