There is no specific limit; it'll depend on available memory and
complexity of the statement. I've run tests with multi-megabyte
string literals, tens of thousands of WHERE clauses, etc.
MySQL's "crashme" test program attempts to discover the maximum length
of a SQL statement in the tested database. The last time I tried it,
I was highly amused to watch the test program run out of memory and dump
core before Postgres did. (This was a couple years back, so maybe
they've fixed their problem by now.)
