README

Build Status

postgresql-dbpatch

PostgreSQL database patch change management extension. This extension supports conducting database changes and deploying them in a robust and automated way.

Installation

To build it, install and check installation, 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

Building Debian packaging

Build the Debian packages using the following command:

make deb

The number of packages built will depend on the number of supported PostgreSQL versions on your system. Make sure to install the postgresql-server-dev-all package, and consider adding the postgresql.org apt repository to get the most versions out of it (see https://wiki.postgresql.org/wiki/Apt

Installing the extension

Once dbpatch 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 dbpatch;

If you want to install dbpatch into a specific schema run:

CREATE EXTENSION dbpatch my_schema;

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

CREATE EXTENSION dbpatch 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/dbpatch.sql

If you want to install dbpatch 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 dbpatch.sql

To simplify the above tasks you may use the dbpatch-loader script which is installed in pg_config --bindir. Syntax is:

dbpatch-loader [--no-extension] [--version <ver>] <dbname> [<schema>]

Dependencies

The dbpatch extension has no dependencies other than PostgreSQL and PL/PgSQL
