Hi, I need to do an operation that I will use some SELECT's and get the results, but I want to have sure that those tables have not been changed with INSERT's or UPDATES during the operation. Example: BEGIN OPERATION Select field from table1; ... Select other_field from table2; ... END OPERATION How can I lock these tables to assure that the tables are not getting INSERTS's or UPDATE's during the operation?
Rather than replicate the docs in a post, I suggest you take a look at: http://www.postgresql.org/docs/9.1/interactive/mvcc.html It explains the various options you have very well.
