Two postgres functions to retrieve param values from OpenNMS events.eventparms column. Tested on postgres 9.4
CREATE OR REPLACE FUNCTION event_pval_num(p_eventparams text, p_param text) RETURNS integer AS $$
BEGIN
RETURN (regexp_matches(p_eventparams,p_param||'=(\d+)'))[1];
END;
$$ LANGUAGE plpgsql;
CREATE OR REPLACE FUNCTION event_pval_txt(p_eventparams text, p_param text) RETURNS text AS $$
BEGIN
RETURN (regexp_matches(p_eventparams,p_param||'=(.*?)\(string'))[1];
END;
