LP#1568046: Replace last two uses of connectby with other function calls.
[working/Evergreen.git] / docs / RELEASE_NOTES_NEXT / Administration / lp1568046-tablefunc-extension-removed.adoc
1 Tablefunc Extension No Longer Required
2 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
3 Changes in the behavior of the connectby function in PostgreSQL 9.5
4 have prompted its removal from the database.  It is easier for
5 Evergreen to maintain compatibility with previous versions of
6 PostgreSQL without this function.
7
8 By eliminating the use of the connectby function, we eliminate the
9 requirement for the tablefunc database extension.  It is no longer
10 installed when the database is created.  If you are upgrading and wish
11 to remove it from your database, you may run the following statement
12 in the database to drop it:
13
14  DROP EXTENSION tablefunc;
