Foreign Data Wrapper for representing CDR files stream as an external SQL table. CDR files from a directory can be read into a table with a specified field-to-column mapping.
Works with PostgreSQL 9.1 and 9.2.
Please consult with doc/multicdr_fdw.md for a function and operator reference.
On PGXN please click on extension from Extensions section to view reference.
To use an extension one must be built, installed into PostgreSQL directory and registered in a database.
Method 1: Using PGXN network
The easisest method to get and install an extension from PGXN network. PGXN client downloads and builds the extension.
pgxn --pg_config <postgresql_install_dir>/bin/pg_config install multicdr_fdw
PGXN client itself is available at github and
can be installed with your favourite method, i.e.
Method 2: Using PGXS makefiles
C extension are best built and installed using PGXS. PGXS ensures that make is performed with needed compiler and flags. You only need GNU make and a compiler to build an extension on an almost any UNIX platform (Linux, Solaris, OS X).
Installation (as superuser):
gmake PG_CONFIG=<postgresql_install_dir>/bin/pg_config install
PostgreSQL server must be restarted.
To uninstall extension completely you may use this command (as superuser):
gmake PG_CONFIG=<postgresql_install_dir>/bin/pg_config uninstall
Project contains SQL tests that can be launched on PostgreSQL with installed extension. Tests are performed on a dynamically created database with a specified user (with the appropriated permissions - create database, for example):
gmake PG_CONFIG=<postgresql_install_dir>/bin/pg_config PGUSER=postgres installcheck
Method 3: Manually
Use this method if you have a precompiled extension and do not want to install this with help of PGXS. Or maybe you just do not have GNU make on a production server. Or if you use Windows (use MSVC 2008 for Postgres 9.1 and MSVC 2010 for Postgres 9.2).
Copy library to the PostgreSQL library directory:
cp multicdr_fdw.so `<postgresql_install_dir>/bin/pg_config --pkglibdir`
Copy control file to the extension directory:
cp multicdr_fdw.control `<postgresql_install_dir>/bin/pg_config --sharedir`/extension
Copy SQL prototypes file to the extension directory:
cp multicdr_fdw--<version>.sql `<postgresql_install_dir>/bin/pg_config --sharedir`/extension
To uninstall extension just remove files you copied before.
Please note that path to the pg_config could be $POSTGRES_DIR/bin/64/pg_config for 64-bit solaris systems.
Creating extension in a database
Extension must be previously installed to a PostgreSQL directory.
Extension is created in a particular database (as superuser):
create extension multicdr_fdw;
It creates all the functions, operators and other stuff from extension. Note that you must restart a server if a previous library was already installed at the same place. In other words, always restart to be sure.
To drop an extension use:
drop extension multicdr_fdw cascade;
