We can only provide limited support for sites using older releases of PostgreSQL; if you require more than we can provide, consider acquiring a commercial support contract. • Platform information the value in a certain column must satisfy a Boolean (truth-value) expression. For instance, to require positive product prices, you could use: CREATE TABLE products ( product_no integer, name text, price the the CHECK constraint for its partition. As we can see, a complex partitioning scheme could require a substantial amount of DDL. In the above example we would be creating a new partition each month0 码力 | 1582 页 | 12.19 MB | 1 年前3

VMware Greenplum 7 Documentationtransaction ID wraparound. VACUUM can now avoid unnecessary heap table truncation attempts that require taking an exclusive table lock even when no truncation is possible. This enhancement avoids unnecessary transactions that involve DDL or DML operations, which are typically the only transactions that require an XID. VMware Greenplum 7 Documentation VMware by Broadcom 166 coordinates distributed transactions however, it is not sufficient for all cases. Applications that do complex queries and updates might require a more rigorously consistent view of the database than READ COMMITTED mode provides. Repeatable0 码力 | 2221 页 | 14.19 MB | 1 年前3
