72bc8208f0 When generating code for partial indexes, be sure not to modify the 
index condition expression in the schema.

2a45cb5c0e Prevent partial indexes on the table on the left hand side of a LEFT JOIN from being incorrectly qualified by a constraint in the ON clause of the join. This relaxes the rule introduced by the previous commit (as the partial indexes on the table on the rhs of the LEFT JOIN may now be qualified by terms within the ON clause).

e006a86643 More test cases to help ensure that partial indexes do not get used if their 
qualifing constraint is inside the ON clause of a LEFT JOIN.

7de2a1faf6 Do not reduce the number of rows scanned at all for "IS NOT NULL" constraints. Fix a bug in calculating the number of rows visited by scans of partial indicies.

87744513e7 Make sure column cache elements are cleared correctly when jumping over

f9c8ce3ced Standardize the error messages generated by constraint failures to a format 
of "$TYPE constraint failed: $DETAIL".  This involves many changes to the
expected output of test cases.

The expression is still not used for anything, however.

1fe0537e51 Here begins an experimental branch for exploring the idea of a partial index. 
This check-in is able to parse a WHERE clause on a CREATE INDEX statement, but
does not actually do anythingn with that WHERE clause yet.
