PL/Parrot 0.04 ============== PL/Parrot is a PostgreSQL procedural language for the Parrot virtual machine. LICENSE INFORMATION =================== This code is distributed under the terms of the Artistic License 2.0. For more details, see the full text of the license in the file LICENSE. Installation ============ For the impatient, to install PL/Parrot into a PostgreSQL database, just do this: make make install make installcheck If you get an error such as: Makefile:13: /usr/lib/postgresql/8.4/lib/pgxs/src/makefiles/pgxs.mk: No such file or directory make: *** No rule to make target `/usr/lib/postgresql/8.4/lib/pgxs/src/makefiles/pgxs.mk'. Stop. then you probably installed postgres from a debian package. You need to install the postgresql-server-dev-X package, where X is your version of PostgreSQL. For example: sudo apt-get install postgresql-server-dev-8.4 To run the tests with pg_prove you should create the plpgsql language in your database. The default database name is your current username, so this should work: createlang plpgsql $USER make test If you encounter an error such as: "Makefile", line 8: Need an operator You need to use GNU make, which may well be installed on your system as 'gmake': gmake gmake install gmake installcheck If you encounter an error such as: make: pg_config: Command not found Be sure that you have `pg_config` installed and in your path. If you used a package management system such as RPM to install PostgreSQL, be sure that the `-devel` package is also installed. If necessary, add the path to `pg_config` to your `$PATH` environment variable: env PATH=$PATH:/path/to/pgsql/bin \ make && make install && make installcheck And finally, if all that fails, copy the entire distribution directory to the `contrib/` subdirectory of the PostgreSQL source tree and try it there without the `$USE_PGXS` variable: make NO_PGXS=1 make install NO_PGXS=1 make installcheck NO_PGXS=1 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 Testing PL/Parrot with PL/Parrot ------------------------ In addition to the PostgreSQL-standard `installcheck` target, the `test` target uses the `pg_prove` Perl program to do its testing, which requires TAP::Harness, included in [Test::Harness](http://search.cpan.org/dist/Test-Harness/ "Test::Harness on CPAN") 3.x. You'll need to make sure that you use a database with PL/pgSQL loaded, or else the tests won't work. `pg_prove` supports a number of environment variables that you might need to use, including all the usual PostgreSQL client environment variables: * `$PGDATABASE` * `$PGHOST` * `$PGPORT` * `$PGUSER` You can use it to run the test suite as a database super user like so: make test PGUSER=postgres Of course, if you're running the tests from the `contrib/` directory, you should add the `NO_PGXS` variable. Adding PL/Parrot to a Database -------------------------- Once PL/Parrot has been built and tested, you can install it into a PL/pgSQL-enabled database: psql -d dbname -f plparrot.sql If you want PL/Parrot to be available to all new databases, install it into the "template1" database: psql -d template1 -f plparrot.sql The `plparrot.sql script will also be installed in the `contrib` directory under the directory output by `pg_config --sharedir`. So you can always do this: psql -d template1 -f `pg_config --sharedir`/contrib/plparrot.sql
