Re: SQL/JSON: functions

Hello hackers,
On branch REL_15_STABLE the following query: SELECT 
JSON_SERIALIZE('{"a":1}' RETURNING jsonb);

produces SIGSEGV for me:
#0  getJsonbOffset (index=39920251, jc=0x563cc5601d5c) at 
jsonb_util.c:148
148                     offset += JBE_OFFLENFLD(jc->children[i]);
