Return the underlying hash used by this HStore instance. |
Use custom marshal loading, since underlying hash uses a default proc.

Use custom marshal dumping, since underlying hash uses a default proc.

Override to force the key argument to a string.
# File lib/sequel/extensions/pg_hstore.rb, line 242 242: def fetch(key, *args, &block) 243: super(key.to_s, *args, &block) 244: end
Append a literalize version of the hstore to the sql.

Return a string containing the unquoted, unstring-escaped literal version of the hstore. Separated out for use by the bound argument code.
