Added fields to PGSQL CDR table

Hello.

After moving from 1.6 to 1.8 we added fields ‘linkedid’ and ‘sequence’ to the PGSQL CDR table structure.

The question is: is it possible to make Asterisk see these two added columns without restarting? I tried to reload/unload+load modules:
app_cdr.so
cdr_pgsql.so
cdr_csv.so (yes, even csv)
func_cdr.so
cdr_pgsql.so
res_config_pgsql.so (yes, even this module, we have ~1000 realtime peers. Though I’m sure it’s not the solution, because has not any relations to CDR, but still…)

So, neither of these actions helped. Asterisk does not see 2 added CDR fields. Only restart helps. Is it normal? It’s better not to prevent accepting of calls in the production environment.

Thanks.
