Temporal Extension for PostgreSQL

This module adds data types, functions, and indexing strategies useful for managing time data in PostgreSQL.

The PERIOD data type represents a range of time, e.g. '[2000-01-01, 2000-03-05)' represents the time from the beginning of January 2000 to the 5th of March.

To build it, just do this:

make
make install
make installcheck

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

And finally, if all that fails (and if you're on PostgreSQL 8.1 or lower, it likely will), copy the entire distribution directory to the contrib/ subdirectory of the PostgreSQL source tree and try it there without pg_config:

env NO_PGXS=1 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

If you are having issues with Postgres on Mac osX and you installed Postgres using the EnterpriseDB install you may want to try using homebrew to install your Postgres Database. The EnterpriseDB install sets up a pg_config that will not work with osX Lion.

Once temporal is installed, you can add it to a database. If you're running PostgreSQL 9.1.0 or greater, it's a simple as connecting to a database as a super user and running:

CREATE EXTENSION temporal;

If you've upgraded your cluster to PostgreSQL 9.1 and already had temporal installed, you can upgrade it to a properly packaged extension with:

CREATE EXTENSION temporal FROM unpackaged;

For versions of PostgreSQL less than 9.1.0, you'll need to run the installation script:

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

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

PGOPTIONS=--search_path=extensions psql -d mydb -f temporal.sql

Dependencies

The temporal data type has no dependencies other than PostgreSQL.
