NAME

6       reindexdb - reindex a PostgreSQL database
7

SYNOPSIS

9       reindexdb [connection-option...] [option...]
10                 [ --schema | -S schema ]...  [ --table | -t table ]...
11                 [ --index | -i index ]...  [dbname]
12
13       reindexdb [connection-option...] [option...] --all | -a
14
15       reindexdb [connection-option...] [option...] --system | -s  [dbname]
16

DESCRIPTION

18       reindexdb is a utility for rebuilding indexes in a PostgreSQL database.
19
20       reindexdb is a wrapper around the SQL command REINDEX(7). There is no
21       effective difference between reindexing databases via this utility and
22       via other methods for accessing the server.
23

OPTIONS

25       reindexdb accepts the following command-line arguments:
26
27       -a
28       --all
29           Reindex all databases.
30
31       [-d] dbname
32       [--dbname=]dbname
33           Specifies the name of the database to be reindexed. If this is not
34           specified and -a (or --all) is not used, the database name is read
35           from the environment variable PGDATABASE. If that is not set, the
36           user name specified for the connection is used.
37
38       -e
39       --echo
40           Echo the commands that reindexdb generates and sends to the server.
41
42       -i index
43       --index=index
44           Recreate index only. Multiple indexes can be recreated by writing
45           multiple -i switches.
46
47       -q
48       --quiet
49           Do not display progress messages.
50
51       -s
52       --system
53           Reindex database's system catalogs.
54
55       -S schema
56       --schema=schema
57           Reindex schema only. Multiple schemas can be reindexed by writing
58           multiple -S switches.
59
60       -t table
61       --table=table
62           Reindex table only. Multiple tables can be reindexed by writing
63           multiple -t switches.
64
65       -v
66       --verbose
67           Print detailed information during processing.
68
69       -V
70       --version
71           Print the reindexdb version and exit.
72
73       -?
74       --help
75           Show help about reindexdb command line arguments, and exit.
76
77       reindexdb also accepts the following command-line arguments for
78       connection parameters:
79
80       -h host
81       --host=host
82           Specifies the host name of the machine on which the server is
83           running. If the value begins with a slash, it is used as the
84           directory for the Unix domain socket.
85
86       -p port
87       --port=port
88           Specifies the TCP port or local Unix domain socket file extension
89           on which the server is listening for connections.
90
91       -U username
92       --username=username
93           User name to connect as.
94
95       -w
96       --no-password
97           Never issue a password prompt. If the server requires password
98           authentication and a password is not available by other means such
99           as a .pgpass file, the connection attempt will fail. This option
100           can be useful in batch jobs and scripts where no user is present to
101           enter a password.
102
103       -W
104       --password
105           Force reindexdb to prompt for a password before connecting to a
106           database.
107
108           This option is never essential, since reindexdb will automatically
109           prompt for a password if the server demands password
110           authentication. However, reindexdb will waste a connection attempt
111           finding out that the server wants a password. In some cases it is
112           worth typing -W to avoid the extra connection attempt.
113
114       --maintenance-db=dbname
115           Specifies the name of the database to connect to discover what
116           other databases should be reindexed. If not specified, the postgres
117           database will be used, and if that does not exist, template1 will
118           be used.
119

ENVIRONMENT

121       PGDATABASE
122       PGHOST
123       PGPORT
124       PGUSER
125           Default connection parameters
126
127       This utility, like most other PostgreSQL utilities, also uses the
128       environment variables supported by libpq (see Section 34.14).
129

DIAGNOSTICS

131       In case of difficulty, see REINDEX(7) and psql(1) for discussions of
132       potential problems and error messages. The database server must be
133       running at the targeted host. Also, any default connection settings and
134       environment variables used by the libpq front-end library will apply.
135

NOTES

137       reindexdb might need to connect several times to the PostgreSQL server,
138       asking for a password each time. It is convenient to have a ~/.pgpass
139       file in such cases. See Section 34.15 for more information.

EXAMPLES

142       To reindex the database test:
143
144           $ reindexdb test
145
146       To reindex the table foo and the index bar in a database named abcd:
147
148           $ reindexdb --table=foo --index=bar abcd
