Обсуждение: problem on truncate for v.7.3.2

On version 7.3.2, 'truncate' can not be executed from pl/pgsql. But it isn't
stated on change notes. Is it a bug?

No, it's a fix.

TRUNCATE, VACUUM, ANALYZE, and REINDEX all perform COMMIT statements as part
of their operation.   If called within a function, this could cause part of
the function to be committed while the rest failed, or even cause a fatal
error.

As such, these statements have been deliberately disabled within PL/pgSQL and
SQL functions.

Note however that TRUNCATE has been reimplemented to be transaction-safe
in 7.4, and so the restriction has gone away again.
