find the material of interest. Just as it is the task of the author to anticipate the items that the readers are most likely to look up, it is the task of the database programmer to foresee which indexes the fraction of rows that match each condition in the WHERE clause. The information used for this task is stored in the pg_statistic system catalog. Entries in pg_statistic are updated by ANALYZE and VACUUM set up appropriate scripts, and to check that they execute successfully. One obvious maintenance task is creation of backup copies of the data on a regular schedule. Without a recent backup, you have0 码力 | 1422 页 | 9.92 MB | 1 年前3PostgreSQL 8.0 Documentation

of the most important advantages of partitioning is precisely that it allows this otherwise painful task to be executed nearly instantaneously by manipulating the partition structure, rather than physically to find the material of interest.
