| <title>Description</title> |
| |
| <para> |
| <application>reindexdb</application> is a utility for rebuilding indexes |
| in a <productname>PostgreSQL</productname> database. |
| </para> |
| |
| <para> |
| <application>reindexdb</application> is a wrapper around the SQL |
| command <xref linkend="SQL-REINDEX" endterm="sql-reindex-title">. |
| There is no effective difference between reindexing databases via |
| this utility and via other methods for accessing the server. |

| In case of difficulty, see <xref linkend="SQL-REINDEX" |
| endterm="sql-reindex-title"> and <xref linkend="APP-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 <application>libpq</application> front-end |

| <title>Notes</title> |
| |
| <para> |
| <application>reindexdb</application> might need to connect several |
| times to the <productname>PostgreSQL</productname> server, asking |
| for a password each time. It is convenient to have a |
| <filename>~/.pgpass</> file in such cases. See <xref |
| linkend="libpq-pgpass"> for more information. |
