This is a user-defined type for unlimited precision integers. It is backed by the OpenSSL library so it should be available on most if not all PostgreSQL installations without the need for another library.
To build it, 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
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
Once bignum 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 bignum;
If you've upgraded your cluster to PostgreSQL 9.1 and already had bignum installed, you can upgrade it to a properly packaged extension with:
CREATE EXTENSION bignum 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/bignum.sql
If you want to install bignum 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 bignum.sql
The bignum data type depends on the OpenSSL library.
