.SH "DESCRIPTION"
.PP
reindexdb
is a utility for rebuilding indexes in a
PostgreSQL
database\&.
.PP
reindexdb
is a wrapper around the SQL command
\fBREINDEX\fR(7)\&. There is no effective difference between reindexing databases via this utility and via other methods for accessing the server\&.
.SH "OPTIONS"
.PP
reindexdb
accepts the following command\-line arguments:
.PP
\fB\-a\fR, \fB\-\-all\fR
.RS 4
Reindex all databases\&.
.RE
.PP
\fB[\-d]\fR\fB \fR\fB\fIdbname\fR\fR, \fB[\-\-dbname=]\fR\fB\fIdbname\fR\fR
.RS 4
Specifies the name of the database to be reindexed\&. If this is not specified and
\fB\-a\fR
(or
\fB\-\-all\fR) is not used, the database name is read from the environment variable
\fBPGDATABASE\fR\&. If that is not set, the user name specified for the connection is used\&.
.RE
.PP
\fB\-e\fR, \fB\-\-echo\fR
.RS 4
Echo the commands that
reindexdb
generates and sends to the server\&.
.RE
.PP
\fB\-i \fR\fB\fIindex\fR\fR, \fB\-\-index=\fR\fB\fIindex\fR\fR
.RS 4
Recreate
\fIindex\fR
only\&.
.RE
.PP
\fB\-q\fR, \fB\-\-quiet\fR
.RS 4
Do not display progress messages\&.
.RE
.PP
\fB\-s\fR, \fB\-\-system\fR
.RS 4
Reindex database\*(Aqs system catalogs\&.
.RE
.PP
\fB\-t \fR\fB\fItable\fR\fR, \fB\-\-table=\fR\fB\fItable\fR\fR
.RS 4
Reindex
\fItable\fR
only\&.
.RE
.PP
\fB\-V\fR, \fB\-\-version\fR
.RS 4
Print the
reindexdb
version and exit\&.
.RE
.PP
\fB\-?\fR, \fB\-\-help\fR
.RS 4
Show help about
reindexdb
command line arguments, and exit\&.
.RE
.PP
reindexdb
also accepts the following command\-line arguments for connection parameters:
.PP
\fB\-h \fR\fB\fIhost\fR\fR, \fB\-\-host=\fR\fB\fIhost\fR\fR
.RS 4
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\&.
.RE
.PP
\fB\-p \fR\fB\fIport\fR\fR, \fB\-\-port=\fR\fB\fIport\fR\fR
.RS 4
Specifies the TCP port or local Unix domain socket file extension on which the server is listening for connections\&.
.RE
.PP
\fB\-U \fR\fB\fIusername\fR\fR, \fB\-\-username=\fR\fB\fIusername\fR\fR
.RS 4
User name to connect as\&.
.RE
.PP
\fB\-w\fR, \fB\-\-no\-password\fR
.RS 4
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\&.
.RE
.PP
\fB\-W\fR, \fB\-\-password\fR
.RS 4
Force
reindexdb
to prompt for a password before connecting to a database\&.
.sp
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
\fB\-W\fR
to avoid the extra connection attempt\&.
.RE
.PP
\fB\-\-maintenance\-db=\fR\fB\fIdbname\fR\fR
.RS 4
Specifies the name of the database to connect to discover what other databases should be reindexed\&. If not specified, the
postgres
database will be used, and if that does not exist,
template1
will be used\&.
.RE
.SH "ENVIRONMENT"
.PP
\fBPGDATABASE\fR, \fBPGHOST\fR, \fBPGPORT\fR, \fBPGUSER\fR
.RS 4
Default connection parameters
.RE
.PP
This utility, like most other
PostgreSQL
utilities, also uses the environment variables supported by
libpq
(see
Section 31.14, \(lqEnvironment Variables\(rq, in the documentation)\&.
.SH "DIAGNOSTICS"
.PP
In case of difficulty, see
\fBREINDEX\fR(7)
and
\fBpsql\fR(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\&.
.SH "NOTES"
.PP
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 31.15, \(lqThe Password File\(rq, in the documentation
for more information\&.
.SH "EXAMPLES"
.PP
To reindex the database
test:
.sp
.if n \{\
.RS 4
.\}
.nf
$ \fBreindexdb test\fR
.fi
.if n \{\
.RE
.\}
.PP
To reindex the table
foo
and the index
bar
in a database named
abcd:
.sp
.if n \{\
.RS 4
.\}
.nf
$ \fBreindexdb \-\-table foo \-\-index bar abcd\fR
.fi
.if n \{\
.RE
.\}
