物理备份是指直接备份数据库文件,包括数据文件、控制文件和日志文件等;而逻辑备份则是通过SQL语句导出数据库中的逻辑对象,如表、视图、存储过程等。 常用的技术包括全量备份和增量备份。全量备份是将整个数据库备份一次,比较适合小型数据库或需要完整恢复的情况;而增量备份则是只备份自上次备份以来发生变化的数据,可以...

UsePREPAREandEXECUTEcommands together. The SQL command is prepared with a user-specified qualifying name. The SQL command runs several times, without the need for re-parsing. PREPARE numplan (int, text, bool) AS INSERT INTO numbers VALUES($1, $2, $3); EXECUTE numplan(100, '...
