Kevin Grittner 5ebeb579b9 Follow-on cleanup for the transition table patch. ... Commit 59702716 added transition table support to PL/pgsql so that SQL queries in trigger functions could access those transient tables. In order to provide the same level of support for PL/perl, PL/python and PL/tcl, refactor the relevant code into a new function SPI_register_trigger_data. Call the new function in the trigger handler of all four PLs, and document it as a public SPI function so that authors of out-of-tree PLs can do the same. Also get rid of a second QueryEnvironment object that was maintained by PL/pgsql. That was previously used to deal with cursors, but the same approach wasn't appropriate for PLs that are less tangled up with core code. Instead, have SPI_cursor_open install the connection's current QueryEnvironment, as already happens for SPI_execute_plan. While in the docs, remove the note that transition tables were only supported in C and PL/pgSQL triggers, and correct some ommissions.
