It is difficult to write standard-compliant code in Postgres.
There are a lot of constructs which have SQL equivalents but are still used
widely, even in samples in docs!

For example, there are suggestions using

now()::CHAR!=foo

while the correct way is

CAST(CURRENT_DATE AS CHAR)<>foo

now() function, :: and != operators should be removed from language.

I like the Python logic: there is one way
Postgres uses C logic: there are multiple ways.

Bruce seems to attempt start  this process trying implement
escape_string_warning in postgresql.conf . However, this is only very minor
step. Please clean Postgres.
