db.Column.flags doesn't work properly??

[Johannes Mueller]

hi, i've tried to program a plugin in LUA, but it seems to me like there is a problem with db.Column.flags. I expected it to return a list of strings, instead it returns a list of userdata. Which means i can not compare the flags with strings like i want:

local i, flag
for i=1, getV.getn(catalog.schemata[x].tables[y].columns[z].flags) do
flag = catalog.schemata[x].tables[y].columns[z].flags
if ( flag == "UNSIGNED" ) do
-- do something
end
end

Am i correct, or do i have to convert it (but how)? I think in the documentation it's mentioned to be a list of strings. But i'm unsure - so i didn't open a Bug report.
