I don't remember seeing any acknowledgement or comments on this. It isn't on
the unapplied patches list either so I'm assuming it got lost somewhere.

Subject: pltcl and plpython memory leak revisited
I have attached two patches as per:
1) pltcl:
Add SPI_freetuptable() calls to avoid memory leaks (Me + Neil Conway)
Change sprintf()s to snprintf()s (Neil Conway)
Remove header files included elsewhere (Neil Conway)
2)plpython:
Add SPI_freetuptable() calls to avoid memory leaks
Cosemtic change to remove a compiler warning
Notes:
I have tested pltcl.c for
a) the original leak problem reported for the repeated call of spi_exec in a
TCL fragment
and b) the subsequent report resulting from the use of spi_exec -array in a TCL
fragment.
The plpython.c patch is exactly the same as that applied to make revision 1.23,
the plpython_schema.sql and feature.expected sections of the patch are also the
same as last submited, applied and subsequently reversed out. It remains
untested by me (other than via make check). However, this should be safe
provided PyString_FromString() _copies_ the given string to make a PyObject.
