Only files within the database cluster directory and the log_directory can be accessed, unless the user is a superuser or is granted the role pg_read_server_files. Tables which have both regular and TOAST pieces will be broken out into separate components; an example showing how you might include those into the main total is available in the documentation, and as of PostgreSQL 9.0 it's possible to include it automatically by using pg_table_size here instead of pg_relation_size: Note that all of the queries below this point on this page show you the sizes for only those objects which are in the database you are currently connected to. These memory contexts will be logged at LOG message level. A transaction can export more than one snapshot, if needed. Inherited tables are grouped together. as in example?

This will either obtain the lock immediately and return true, or return false without waiting if the lock cannot be acquired immediately. Converts a write-ahead log location to the name of the WAL file holding that location. Note, however, that the actual number of rows returned may be larger, since this limit is only checked after adding the rows produced when decoding each new transaction commit.
