38.18. `pga_proxy_table` #

This metadata table contains information about proxy tables. For more information about proxy tables, refer to Chapter 22.

Column Name	Column Type	Constraint	Description
`proxy_table_id`	`BIGINT`	Primary key	The proxy table ID.
`proxy_table_name`	`VARCHAR`	`NOT NULL`	The proxy table name identifying the associated pgpro_metastore object. The name is in the following format: `prefix`_`object_name`_`object_number` Where: `prefix`: The prefix that determines the type of the pgpro_metastore object. Possible values: `s` for storages `t` for analytical tables `f` for shared directories `object_name`: The first 22 characters of the pgpro_metastore object name. `object_number`: A sequence number for the pgpro_metastore object. Since the `object_name` is limited to the first 22 characters, this number allows distinguishing pgpro_metastore objects whose names start with the same characters. Examples of proxy table names: `s_localstorage_00001` `t_hits_00002` `f_shared_00001`
