On second thought, => might actually be a very intuitive syntax for
defining dictionary types like hstore and json, since it matches PHP's
associative array syntax, as in:
hstore('key1' => 'value1', 'key2' => 'value2') -- hypothetical SQL
array('key1' => 'value1', 'key2' => 'value2') // PHP
That way, when people see =>, they can think "dictionary" whether
they're in PHP or SQL.
Note that this is a bit different than what I suggested earlier:
hstore(key1 => 'value1', key2 => 'value2')
Identifier names were used instead of literal names, which conflicts
with the other approach. Also, the other approach is more flexible,
as the user can generate names with expressions at runtime.
