Description
reindexdb is a utility for rebuilding indexes in a PostgreSQL database.
reindexdb is a wrapper around the SQL command
REINDEX
. 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.
-
-s
--system
-
Reindex database's system catalogs.
-
-t
table
--table
table
-
Reindex
table
only.
-
-i
index
--index
index
-
Recreate
index
only.
-
[-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.
-
-q
--quiet
-
Do not display a response.
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
--password
-
Force password prompt.
Environment
-
PGDATABASE
PGHOST
PGPORT
PGUSER
-
Default connection parameters
Diagnostics
In case of difficulty, see
REINDEX
and
psql
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 Section 28.12 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
