Patch for current_schemas to optionally include implicit ...

Browse Source 
Second cut attached. This one just adds a boolean option to the existing
function to indicate that implicit schemas are to be included (or not).
I remembered the docs as well this time :-)

at the front of the search path (or NULL if the search path is
empty). This is the schema that will be used for any tables or
other named objects that are created without specifying a target schema.
<function>current_schemas</function> returns an array of the names of all
schemas presently in the search path. Note that these functions show
only schemas that are explicitly part of the path; when a system schema
is being searched implicitly, it is not listed.
<function>current_schemas(boolean)</function> returns an array of the names of all
schemas presently in the search path. The boolean option determines whether or not
implicitly included system schemas such as pg_catalog are included in the search
path returned.
