PostgreSQL Client
|
||
|
|
|
||
|
|
Connect to a PostgreSQL database and run queries. This is not intended to be a general purpose client but is suitable for
|
||
|
|
pgBackRest's limited needs. In particular, data type support is limited to text, int, and bool types so it may be necessary to add
|
||
|
|
casts to queries to output one of these types.
