extend self
# Returns an array of <tt>[schema_name, table_name]</tt> extracted from +name+.
# +schema_name+ is nil if not specified in +name+.
# +schema_name+ and +table_name+ exclude surrounding quotes (regardless of whether provided in +name+)
# +name+ supports the range of schema/table references understood by PostgreSQL, for example:
#
# * <tt>table_name</tt>
# * <tt>"table.name"</tt>
# * <tt>schema_name.table_name</tt>
# * <tt>schema_name."table.name"</tt>
# * <tt>"schema_name".table_name</tt>
# * <tt>"schema.name"."table name"</tt>
