Stream triggers row variables v5
TG_NAME
Data type name. This variable contains the name of the trigger actually fired. The actual trigger name has a '_bdrt' or '_bdrc' suffix (depending on trigger type) compared to the name provided during trigger creation.
TG_WHEN
Data type text. This variable says BEFORE for both conflict and transform triggers.
You can get the stream trigger type by calling the bdr.trigger_get_type()
information function. See bdr.trigger_get_type.
TG_LEVEL
Data type text: a string of ROW.
TG_OP
Data type text: a string of INSERT, UPDATE, or DELETE identifying the operation for which the trigger was fired.
TG_RELID
Data type oid: the object ID of the table that caused the trigger invocation.
TG_TABLE_NAME
Data type name: the name of the table that caused the trigger invocation.
TG_TABLE_SCHEMA
Data type name: the name of the schema of the table that caused the trigger invocation. For partitioned tables, this is the name of the root table.
TG_NARGS
Data type integer: the number of arguments given to the trigger function in
the bdr.create_conflict_trigger() or bdr.create_transform_trigger()
statement.
TG_ARGV[]
Data type array of text: the arguments from the bdr.create_conflict_trigger()
or bdr.create_transform_trigger() statement. The index counts from 0.
Invalid indexes (less than 0 or greater than or equal to TG_NARGS) result in
a NULL value.
