Return the serialized payload of loaded libraries.

command.
For more information please refer to Introduction to Redis Functions.
Examples
The following example shows how to dump loaded libraries using FUNCTION DUMP
and then it calls FUNCTION FLUSH
deletes all the libraries.
Then, it restores the original libraries from the serialized payload with FUNCTION RESTORE
.
redis> FUNCTION DUMP
"\xf6\x05mylib\x03LUA\x00\xc3@D@J\x1aredis.register_function('my@\x0b\x02', @\x06`\x12\x11keys, args) return`\x0c\a[1] end)\n\x00@\n)\x11\xc8|\x9b\xe4"
redis> FUNCTION FLUSH
OK
redis> FUNCTION RESTORE "\xf6\x05mylib\x03LUA\x00\xc3@D@J\x1aredis.register_function('my@\x0b\x02', @\x06`\x12\x11keys, args) return`\x0c\a[1] end)\n\x00@\n)\x11\xc8|\x9b\xe4"
OK
