.SH "DESCRIPTION"
.PP
\fBreindexdb\fR is a utility for rebuilding indexes
in a PostgreSQL database.
.PP
\fBreindexdb\fR is a wrapper around the SQL
command REINDEX [\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
\fBreindexdb\fR accepts the following command-line arguments:
.TP
\fB-a\fR
.TP
\fB--all\fR
Reindex all databases.
.TP
\fB-s\fR
.TP
\fB--system\fR
Reindex database's system catalogs.
.TP
\fB-t \fItable\fB\fR
.TP
\fB--table \fItable\fB\fR
Reindex \fItable\fR only.
.TP
\fB-i \fIindex\fB\fR
.TP
\fB--index \fIindex\fB\fR
Recreate \fIindex\fR only.
.TP
\fB[-d] \fIdbname\fB\fR
.TP
\fB[--dbname] \fIdbname\fB\fR
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.
.TP
\fB-e\fR
.TP
\fB--echo\fR
Echo the commands that \fBreindexdb\fR generates
and sends to the server.
.TP
\fB-q\fR
.TP
\fB--quiet\fR
Do not display a response.
.PP
.PP
\fBreindexdb\fR also accepts 
the following command-line arguments for connection parameters:
.TP
\fB-h \fIhost\fB\fR
.TP
\fB--host \fIhost\fB\fR
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.
.TP
\fB-p \fIport\fB\fR
.TP
\fB--port \fIport\fB\fR
Specifies the TCP port or local Unix domain socket file 
extension on which the server
is listening for connections.
.TP
\fB-U \fIusername\fB\fR
.TP
\fB--username \fIusername\fB\fR
User name to connect as.
.TP
\fB-W\fR
.TP
\fB--password\fR
Force password prompt.
.PP
.SH "ENVIRONMENT"
.TP
\fBPGDATABASE\fR
.TP
\fBPGHOST\fR
.TP
\fBPGPORT\fR
.TP
\fBPGUSER\fR
Default connection parameters
.PP
This utility, like most other PostgreSQL utilities,
also uses the environment variables supported by \fBlibpq\fR
(see in the documentation).
.PP
.SH "DIAGNOSTICS"
.PP
In case of difficulty, see REINDEX [\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 \fBlibpq\fR front-end
library will apply.
.SH "NOTES"
.PP
\fBreindexdb\fR might need to connect several
times to the PostgreSQL server, asking
for a password each time. It is convenient to have a
\fI~/.pgpass\fR file in such cases. See in the documentation for more information.
.SH "EXAMPLES"
.PP
To reindex the database test:
.sp
.nf
$ \fBreindexdb test\fR
.sp
.fi
.PP
To reindex the table foo and the index
bar in a database named abcd:
.sp
.nf
$ \fBreindexdb --table foo --index bar abcd\fR
.sp
.fi
