Title: High Performance PostgreSQL for Rails (p. 177)
Example: Typo on page

Page 177 has the following sentence:

For active deleted rows, since they represent the biggest proportion—the majority of rows—PostgreSQL would likely load the whole table with a sequential scan and then filter out the smaller proportion of soft-deleted rows.

The sentence should read: For active rows, since they represent the biggest proportion—the majority of rows—PostgreSQL would likely load the whole table with a sequential scan and then filter out the smaller proportion of soft-deleted rows.

Thanks for noticing this and reporting it @martinstreicher. I’ve just submitted a correction to remove the word “deleted” from this line here. Hopefully it makes it into an upcoming print version soon.
