postgresql字符串转timestamp without time zone

主表postgresql有两个时间字段

datatime(年月日时分秒)，字段类型timestamp without time zone

minisecond，字段类型numeric

现在将两个字段拼接为一个字段，字段类型timestamp without time zone,用to_timestamp会直接转为timestamp with time zone

正确sql:

create or replace view *** as

select concat(datatime,'.',minisecond):: timestamp without time zone as datatime from table
