bd42642431 In partial index scans, if the WHERE clause implies a constant value for a table column, replace occurences of that table column with the constant. This increases the likelihood of the partial index being a covering index.

658096e124 The view-scan optimization was added to enhance the performance of one specific 
query, but it causes performance regressions on a host of others.  Disable it
(at least temporarily) in order to try to find an alternative way of fixing the
one specific query that it was created to fix - an alternative way that does
not cause performance problems for other unrelated queries.

e744f66008 According to [forum:/forumpost/9f6db917e1|forum post 9f6db917e1], older 
MSVC compilers are unable to convert a double directly into an unsigned
long long int, but must first go through a signed long long int.  Work
around this by restricting the range of doubles that are converted into
long long integers so that only the lower 63 bits are used.

double really does provide extra precision.

for the minimum cell enlargement if the enlargement is non-zero for all cells.
