ALTER EXTENSION changes the definition of an installed
extension. There are several subforms:
UPDATEThis form updates the extension to a newer version. The extension must supply a suitable update script (or series of scripts) that can modify the currently-installed version into the requested version.
SET SCHEMAThis form moves the extension's objects into another schema. The extension has to be relocatable for this command to succeed.
ADD member_objectThis form adds an existing object to the extension. This is mainly useful in extension update scripts. The object will subsequently be treated as a member of the extension; notably, it can only be dropped by dropping the extension.
DROP member_objectThis form removes a member object from the extension. This is mainly useful in extension update scripts. The object is not dropped, only disassociated from the extension.
See Section 36.17 for more information about these operations.
You must own the extension to use ALTER EXTENSION.
The ADD/DROP forms require ownership of the
added/dropped object as well.
nameThe name of an installed extension.
new_version
The desired new version of the extension. This can be written as
either an identifier or a string literal. If not specified,
ALTER EXTENSION UPDATE attempts to update to whatever is
shown as the default version in the extension's control file.
new_schemaThe new schema for the extension.
object_nameaggregate_namefunction_nameoperator_nameprocedure_nameroutine_nameThe name of an object to be added to or removed from the extension. Names of tables, aggregates, domains, foreign tables, functions, operators, operator classes, operator families, procedures, routines, sequences, text search objects, types, and views can be schema-qualified.
source_typeThe name of the source data type of the cast.
target_typeThe name of the target data type of the cast.
argmode
The mode of a function, procedure, or aggregate
argument: IN, OUT,
INOUT, or VARIADIC.
If omitted, the default is IN.
Note that ALTER EXTENSION does not actually pay
any attention to OUT arguments, since only the input
arguments are needed to determine the function's identity.
So it is sufficient to list the IN, INOUT,
and VARIADIC arguments.
argname
The name of a function, procedure, or aggregate argument.
Note that ALTER EXTENSION does not actually pay
any attention to argument names, since only the argument data
types are needed to determine the function's identity.
argtypeThe data type of a function, procedure, or aggregate argument. The use of the date type is described in lightdb_oracle_type_date_to_oracle_date.
left_typeright_type
The data type(s) of the operator's arguments (optionally
schema-qualified). Write NONE for the missing argument
of a prefix or postfix operator.
PROCEDURALThis is a noise word.
ALTER EXTENSION is a LightDB
extension.
