fix: mitigate SQLSTATE42P01 errors BED-5742

[urangel]

Queries that contain bound right nodes that are referenced in a different frame result in translations that surface the SQLSTATE42P01 error upon query execution. Selectivity optimization rewrites that flip query directions seem to be part of the underlying issue.

This fix mitigates these errors in some queries that are experiencing the issue by increasing the selectivity measure for bound nodes which decreases the chance of a query rewrite.

While these changes prevent errors in some of the queries noted in the issue there are other discrepancies that may still be related to bound right nodes not joining correctly.

Fixes:

• Error noted in BED-5712
• Error noted in BED-5418
• Error noted in BP-1687

Does not fix:

• result sets with edges that are only a partial match
• result sets that do not uphold terminal node constraints across recursive expansion
• BED-5463
• BP-1573
• BP-1590
