Note: At present, this section is just taken from PostgreSQL documentation and is subject to revision for Postgres-XC.
The global dictionary SD is available to store data between function calls. This variable is private static data. The global dictionary GD is public data, available to all Python functions within a session. Use with care.
Each function gets its own execution environment in the
Python interpreter, so that global data and function arguments from
myfunc
are not available to
myfunc2
. The exception is the data in the
GD dictionary, as mentioned above.
