[SR-Users] getting unexpected values from htable

Hi all I'm testing the htable module at Kamailio 3.1. Currently it's an extremely simple table with a single row loaded from a postgres DB. These are the relevant lines in the configuration file: modparam("htable", "db_url", "postgres://user:password@localhost :5432/database") modparam("htable", "htable", "a=>size=2;autoexpire=0;dbtable=h_table;") modparam("htable", "key_name_column", "key_name") modparam("htable", "key_type_column", "key_type") modparam("htable", "value_type_column", "value_type") modparam("htable", "key_value_column", "key_value") The only line in the table is: key_name | key_value | key_type | value_type ----------+-----------+----------+------------ 5 | 1 | 1 | 0 However, sht_print() shows this: 0(8570) ERROR: htable [ht_api.c:488]: ===== htable[a] hid: 109 exp: 0> 0(8570) ERROR: htable [ht_api.c:492]: htable[0] -- <0> 0(8570) ERROR: htable [ht_api.c:492]: htable[1] -- <0> 0(8570) ERROR: htable [ht_api.c:492]: htable[2] -- <0> 0(8570) ERROR: htable [ht_api.c:492]: htable[3] -- <1> 0(8570) ERROR: htable [ht_api.c:496]: cell: 5 0(8570) ERROR: htable [ht_api.c:498]: hid: 51 msize: 74 flags: 0 expire: 0 0(8570) ERROR: htable [ht_api.c:502]: v-i:9585128 Any idea of what might be happening? Thanks in advance.
