Fix typos in various code comments in the includes directory

Found total 4 occurrences of the same typo

tameeshb@imt3rabyt3 /v/w/h/drupal7> grep -r 'Retrive' .
./includes/database/pgsql/database.inc:   * Retrive a the next id in a sequence.
./includes/database/pgsql/database.inc:    // Retrive the name of the sequence. This information cannot be cached
./includes/database/pgsql/database.inc:    // Retrive the next id. We know this will be as high as we want it.
./includes/database/schema.inc:    // Retrive the table name and schema

I have tested the patch #4 at my end and it fixes the spelling mistake.
Works as expected.

Hi guys.

I was analyzing it and it really makes sense. Good catch.

Good Work.

Regards.

Committed to 7.x - thanks!

I reverted or changed a couple of these on commit, though:

I reverted this change, since the original ("diffed") was actually correct here.

I fixed that additional grammatical error on the same line.

Same here - I fixed that additional grammatical error on the same line.
