CREATELANG(1) PostgreSQL Client Applications CREATELANG(1) NAME
createlang - define a new PostgreSQL procedural language SYNOPSIS
createlang [ connection-options... ] langname [ dbname ] createlang [ connection-options... ] --list | -l dbname DESCRIPTION
createlang is a utility for adding a new programming language to a PostgreSQL database. createlang can handle all the languages supplied in the default PostgreSQL distribution, but not languages provided by other parties. Although backend programming languages can be added directly using several SQL commands, it is recommended to use createlang because it performs a number of checks and is much easier to use. See CREATE LANGUAGE [create_language(7)] for additional information. OPTIONS
createlang accepts the following command-line arguments: langname Specifies the name of the procedural programming language to be defined. [-d] dbname [--dbname] dbname Specifies to which database the language should be added. The default is to use the database with the same name as the current sys- tem user. -e --echo Displays SQL commands as they are executed. -l --list Shows a list of already installed languages in the target database (which must be specified). -L directory Specifies the directory in which the language interpreter is to be found. The directory is normally found automatically; this option is primarily for debugging purposes. createlang also accepts the following command-line arguments for connection parameters: -h host --host host Specifies the host name of the machine on which the server is running. If host begins with a slash, it is used as the directory for the Unix domain socket. -p port --port port Specifies the Internet TCP/IP port or local Unix domain socket file extension on which the server is listening for connections. -U username --username username User name to connect as -W --password Force password prompt. ENVIRONMENT
PGDATABASE PGHOST PGPORT PGUSER Default connection parameters. DIAGNOSTICS
Most error messages are self-explanatory. If not, run createlang with the --echo option and see under the respective SQL command for details. Check also under psql(1) for more possibilities. NOTES
Use droplang(1) to remove a language. createlang is a shell script that invokes psql several times. If you have things arranged so that a password prompt is required to connect, you will be prompted for a password several times. EXAMPLES

REINDEXDB(1) PostgreSQL Client Applications REINDEXDB(1) NAME
reindexdb - reindex a PostgreSQL database SYNOPSIS
reindexdb [ connection-option... ] [ --table | -t table ] [ --index | -i index ] [ dbname ] reindexdb [ connection-option... ] [ --all | -a ] reindexdb [ connection-option... ] [ --system | -s ] [ dbname ] DESCRIPTION
reindexdb is a utility for rebuilding indexes in a PostgreSQL database. reindexdb is a wrapper around the SQL command REINDEX [reindex(7)]. There is no effective difference between reindexing databases via this utility and via other methods for accessing the server. OPTIONS
reindexdb accepts the following command-line arguments: -a --all Reindex all databases. [-d] dbname [--dbname] dbname Specifies the name of the database to be reindexed. If this is not specified and -a (or --all) is not used, the database name is read from the environment variable PGDATABASE. If that is not set, the user name specified for the connection is used. -e --echo Echo the commands that reindexdb generates and sends to the server. -i index --index index Recreate index only. -q --quiet Do not display progress messages. -s --system Reindex database's system catalogs. -t table --table table Reindex table only. reindexdb also accepts the following command-line arguments for connection parameters: -h host --host host Specifies the host name of the machine on which the server is running. If the value begins with a slash, it is used as the directory for the Unix domain socket. -p port --port port Specifies the TCP port or local Unix domain socket file extension on which the server is listening for connections. -U username --username username User name to connect as. -w --no-password Never issue a password prompt. If the server requires password authentication and a password is not available by other means such as a .pgpass file, the connection attempt will fail. This option can be useful in batch jobs and scripts where no user is present to enter a password. -W --password Force reindexdb to prompt for a password before connecting to a database. This option is never essential, since reindexdb will automatically prompt for a password if the server demands password authentica- tion. However, reindexdb will waste a connection attempt finding out that the server wants a password. In some cases it is worth typing -W to avoid the extra connection attempt. ENVIRONMENT
PGDATABASE PGHOST PGPORT PGUSER Default connection parameters This utility, like most other PostgreSQL utilities, also uses the environment variables supported by libpq (see in the documentation). DIAGNOSTICS
In case of difficulty, see REINDEX [reindex(7)] and psql(1) for discussions of potential problems and error messages. The database server must be running at the targeted host. Also, any default connection settings and environment variables used by the libpq front-end library will apply. NOTES
reindexdb might need to connect several times to the PostgreSQL server, asking for a password each time. It is convenient to have a ~/.pgpass file in such cases. See in the documentation for more information. EXAMPLES
To reindex the database test: $ reindexdb test To reindex the table foo and the index bar in a database named abcd: $ reindexdb --table foo --index bar abcd SEE ALSO
