pllu.init - module

[hellower]

I am very grateful for the pllua module.

Should I insert only the pllua"U" module at pllua.init table?
plla"U" module is not allowed in pllua.init table

ex)
luarocks install http -- this modue inclde "IO" module. --- untrusted!

sql> insert into pllua.init values('http.request');
sql>
CREATE OR REPLACE FUNCTION f_debug()
RETURNS integer AS

return 1234;

----------- http module dependencies-------------------
https://github.com/daurnimator/lua-http
Dependencies
cqueues >= 20161214
luaossl >= 20161208
basexx >= 0.2.0
lpeg
lpeg_patterns >= 0.3
fifo
To use gzip compression you need one of:
lzlib or lua-zlib
If using lua < 5.3 you will need
compat-5.3 >= 0.3 ------------------ !!!!
If using lua 5.1 you will need
luabitop (comes with LuaJIT) or a backported bit32_

-- my suggestion ----------------------------

CREATE TABLE pllua.init
(
module text
,trusted boolean -- new column
);
insert into pllua.init values('http.client, false);

sorry for poor english.
