Hi All, I am a beginner in Postgresql and Databases. I have a requirement that reclaiming disk space by deleting the rows in a selected time span. I went through the documents and articles to know how to get the table size (http://wiki.postgresql.org/wiki/Disk_Usage)
But before let the user delete, I have to show the size of the records size in the selected time span. But here I don't know how to calculate the selected records size. In addition to this, I assume that after deleted the records I have to run VACUUM FULL command to reclaiming the space( Please correct me if I am wrong or let me know the best approach) . The table looks like this CREATE TABLE IF NOT EXISTS "SN_SamplTable" ( "ID" integer NOT NULL, "Data" integer, "CLIENT_COUNT_TIMESTAMP" timestamp without time zone ); Please help me to how to proceed on this. Thanks & Regards, Ramkumar.
