resetsequence 1.0.0

This module contains a single PostgreSQL extension, comprising simple utility functions that help with maintaining sequence values. These functions let you reset the sequences to the maximum values used in table columns that link to them via DEFAULT clauses.

To build it, just do this:

make
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

Once resetsequente 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 resetsequence;

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

CREATE EXTENSION resetsequence 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/resetsequence--1.0.sql

If you want to install resetsequence 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 resetsequence.sql

Dependencies

The resetsequence module has no dependencies other than PostgreSQL.
