Description
reindexdb is a utility for rebuilding indexes in a Postgres Pro 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.
[-d]
dbname
[--dbname=]
dbname
Specifies the name of the database to be reindexed, when
-a
/--all
is not used. If this is not specified, the database name is read from the environment variablePGDATABASE
. If that is not set, the user name specified for the connection is used. Thedbname
can be a connection string. If so, connection string parameters will override any conflicting command line options.-e
--echo
Echo the commands that reindexdb generates and sends to the server.
-i
index
--index=
index
Recreate
index
only. Multiple indexes can be recreated by writing multiple-i
switches.-q
--quiet
Do not display progress messages.
-s
--system
Reindex database's system catalogs only.
-S
schema
--schema=
schema
Reindex
schema
only. Multiple schemas can be reindexed by writing multiple-S
switches.-t
table
--table=
table
Reindex
table
only. Multiple tables can be reindexed by writing multiple-t
switches.-v
--verbose
Print detailed information during processing.
-V
--version
Print the reindexdb version and exit.
-?
--help
Show help about reindexdb command line arguments, and exit.
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 authentication. 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.--maintenance-db=
dbname
Specifies the name of the database to connect to to discover which databases should be reindexed, when
-a
/--all
is used. If not specified, thepostgres
database will be used, or if that does not exist,template1
will be used. This can be a connection string. If so, connection string parameters will override any conflicting command line options. Also, connection string parameters other than the database name itself will be re-used when connecting to other databases.
Environment
PGDATABASE
PGHOST
PGPORT
PGUSER
Default connection parameters
This utility, like most other Postgres Pro utilities, also uses the environment variables supported by libpq (see Section 31.14).
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 Postgres Pro server, asking for a password each time. It is convenient to have a ~/.pgpass
file in such cases. See Section 31.15 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
