In Postgres, the functions likeNOW(),CURRENT_TIMESTAMP,TRANSACTION_TIMESTAMP(), etc., retrieve the current date and time with time zone information. However, if we use them for the TIMESTAMP column, then the timezone information will be skipped, and the date time values will be inserted in...
In Postgres, a time zone represents a region of the earth with a uniform standard time. Time zones allow us to convert local time to UTC(Coordinated Universal Time) or vice versa. Time with time zone is stored in PostgreSQL as a TIMESTAMPTZ(abbreviation of TIMESTAMP with TIMEZONE) data t...
当然,pg中+08时区的时区标识符还有其他(如下),也可以用来做为中国localtime的时区。 postgres=#select*frompg_timezone_nameswhereutc_offset='08:00:00'; name|abbrev|utc_offset|is_dst---+---+---+---Asia/Makassar|WITA|08:00:00|f Asia/Kuching|+08|08:00:00|f Asia/Ulaanbaatar|+08|08:00:...
在PostgreSQL中,有一个功能叫做文件复制(File Replication),可以用于将一个数据库实例的更改传输到另一个实例。 "timestamp with timezone"是PostgreSQL中的一种数据类型,用于存储带有时区信息的时间戳数据。它允许用户在存储和检索时间数据时考虑到时区的差异。 当使用文件复制功...

However, when, for example, you view a timestamptz value, it must be converted to text—and this conversion is sensitive to the session timezone. Clock time is measured in hours, minutes, and seconds—which units are mutually reliably convertible, just as are yards, feet and inches. These...
