pg_cursors

The pg_cursors view lists the currently available cursors. Cursors can be defined in one of the following ways:

via the DECLARE SQL statement;
via the Bind message in the frontend/backend protocol;
via the Server Programming Interface (SPI).

NOTE

Greengage DB does not allow defining or accessing parallel retrieve cursors via SPI.

Cursors exist only for the duration of the transaction that defines them, unless they have been declared WITH HOLD. Non-holdable cursors are only present in the view until the end of their creating transaction.

NOTE

Greengage DB does not support holdable parallel retrieve cursors.

Column Type Description

Column	Type	Description
name	text	The name of the cursor
statement	text	The verbatim query string submitted to declare this cursor
is_holdable	boolean	`true` if the cursor is holdable (that is, it can be accessed after the transaction that declared the cursor has committed); `false` otherwise. NOTE Greengage DB does not support holdable parallel retrieve cursors, this value is always `false` for such cursors.
is_binary	boolean	`true` if the cursor was declared `BINARY`; `false` otherwise
is_scrollable	boolean	`true` if the cursor is scrollable (that is, it allows rows to be retrieved in a nonsequential manner); `false` otherwise. NOTE Greengage DB does not support scrollable cursors, this value is always `false`.
creation_time	timestamptz	The time at which the cursor was declared
