In preparation for adding write-ahead logging to hash indexes, refactor _hash_freeovflpage and _hash_squeezebucket so that all related page modifications happen in a single section of code. The previous coding assumed that it would be fine to move tuples one at a time, and also that the various operations involved in freeing an overflow page didn't necessarily all need to be done together, all of which is true if you don't care about write-ahead logging. Amit Kapila, with slight changes by me. |
