citext 2.0.2

This distribution creates a custom PostgreSQL data type, CITEXT, a locale- aware, case-insensitve TEXT type for PostgreSQL 8.3. Essentially, it internally calls LOWER() when comparing values. Otherwise, it behaves exactly like TEXT.

If you're running PostgreSQL 8.4 or higher, don't use this extension. Use the core citext module instead.

If you're using PostgreSQL 8.2 or lower, this extension will not work. You might be interested in citext 1.0, though be aware that it is not locale-aware and case-insensitively compares only ASCII characters.

If, on the other hand, you're running PostgreSQL 8.3, this is the extension for you

Installation

To build citext, just do this:

make
make installcheck
make install

If you encounter an error such as:

"Makefile", line 8: Need an operator

You need to use GNU make, which may well be installed on your system as gmake:

gmake
gmake install
gmake installcheck

If you encounter an error such as:

make: pg_config: Command not found

Be sure that you have pg_config installed and in your path. If you used a package management system such as RPM to install PostgreSQL, be sure that the -devel package is also installed. If necessary tell the build process where to find it:

env PG_CONFIG=/path/to/pg_config make && make installcheck && make install

If you encounter an error such as:

ERROR:  must be owner of database regression

You need to run the test suite using a super user, such as the default "postgres" super user:

make installcheck PGUSER=postgres

Once citext is installed, you can add it to a database by running the installation script:

psql -d mydb -f /path/to/pgsql/share/contrib/citext.sql

If you want to install citext and all of its supporting objects into a specific schema, use the PGOPTIONS environment variable to specify the schema, like so:

PGOPTIONS=--search_path=contrib psql -d mydb -f citext.sql

Dependencies

The citext data type has no dependencies other than PostgreSQL 8.3.
