Re: Tricking the optimizer

[Vitaliy Garnashevich]

We'd rather avoid writing C code. We're trying to stick with the DB 
functionality provided by default.

Could something like the following, in theory, make things at least 
somewhat better in our case (without using the selectivity override)?

... WHERE coalesce(securityFilter1 AND securityFilter2 AND 
securityFilter3)::bool;
