Support Gist index ops

[wangjie-star]

Enhancement

If the PG data type corresponding to the compatible Oracle data type supports Gist index or GIN index, these Oracle data types should also support the corresponding index operator.
The indexing operators that should be supported are as follows:

oprname	oprleft	oprright
<	number	number
<=	number	number
=	number	number
>=	number	number
>	number	number
<>	number	number

The above is the Gist index operator of the "number" data type to be implemented.

oprname	oprleft	oprright
<	varchar2	varchar2
<=	varchar2	varchar2
=	varchar2	varchar2
>=	varchar2	varchar2
>	varchar2	varchar2
<>	varchar2	varchar2

The above is the Gist index operator of the "varchar2" data type to be implemented.

oprname	oprleft	oprright
<	binary_float	binary_float
<=	binary_float	binary_float
=	binary_float	binary_float
>=	binary_float	binary_float
>	binary_float	binary_float
<>	binary_float	binary_float
<->	binary_float	binary_float

The above is the Gist index operator of the "binary_float" data type to be implemented.

oprname	oprleft	oprright
<	binary_double	binary_double
<=	binary_double	binary_double
=	binary_double	binary_double
>=	binary_double	binary_double
>	binary_double	binary_double
<>	binary_double	binary_double
<->	binary_double	binary_double

The above is the Gist index operator of the "binary_double" data type to be implemented.

oprname	oprleft	oprright
<	date	date
<=	date	date
=	date	date
>=	date	date
>	date	date
<>	date	date
<->	date	date

The above is the Gist index operator of the "date" data type to be implemented.

oprname	oprleft	oprright
<	timestamp	timestamp
<=	timestamp	timestamp
=	timestamp	timestamp
>=	timestamp	timestamp
>	timestamp	timestamp
<>	timestamp	timestamp
<->	timestamp	timestamp

The above is the Gist index operator of the "timestamp" data type to be implemented.

oprname	oprleft	oprright
<	timestamp with time zone	timestamp with time zone
<=	timestamp with time zone	timestamp with time zone
=	timestamp with time zone	timestamp with time zone
>=	timestamp with time zone	timestamp with time zone
>	timestamp with time zone	timestamp with time zone
<>	timestamp with time zone	timestamp with time zone
<->	timestamp with time zone	timestamp with time zone

The above is the Gist index operator of the "timestamp with time zone" data type to be implemented.

oprname	oprleft	oprright
<	timestamp with local time zone	timestamp with local time zone
<=	timestamp with local time zone	timestamp with local time zone
=	timestamp with local time zone	timestamp with local time zone
>=	timestamp with local time zone	timestamp with local time zone
>	timestamp with local time zone	timestamp with local time zone
<>	timestamp with local time zone	timestamp with local time zone
<->	timestamp with local time zone	timestamp with local time zone

The above is the Gist index operator of the "timestamp with local time zone" data type to be implemented.

oprname	oprleft	oprright
<	interval year to month	interval year to month
<=	interval year to month	interval year to month
=	interval year to month	interval year to month
>=	interval year to month	interval year to month
>	interval year to month	interval year to month
<>	interval year to month	interval year to month
<->	interval year to month	interval year to month

The above is the Gist index operator of the "interval year to month" data type to be implemented.

oprname	oprleft	oprright
<	interval day to second	interval day to second
<=	interval day to second	interval day to second
=	interval day to second	interval day to second
>=	interval day to second	interval day to second
>	interval day to second	interval day to second
<>	interval day to second	interval day to second
<->	interval day to second	interval day to second

The above is the Gist index operator of the "interval day to second" data type to be implemented.
