Dear friends,
I would like to use ltree for search paths in a warehouse application, something like "Material-Entry-01.Main-Aisle.Shelf-Aisle-R07/R08.R07-12-03"
Unfortunately I can not use common separators like dash (-) or slash(/)
Documentation states only thes characters
[A-Za-z0-9_] are allowed.https://www.postgresql.org/docs/10/static/ltree.htmlAs far as I can see this limitation is set in source code of ltree, line 83: https://doxygen.postgresql.org/ltree_8h_source.html
#define ISALNUM(x) ( t_isalpha(x) || t_isdigit(x) || ( pg_mblen(x) == 1 && t_iseq((x), '_') ) )
I would appreciate if at least the dash (-) and perhaps also the slash(/) would be included to the list of allowed characters.
It is not only me, also other users are interested in this feature, some of them even changed the source code themselves to recompile their own Postgresql version..
best regards
