Swap max costing values to align with upstream guidance ( #658 )
...
A feature targeted for PostgreSQL 18 (postgres/postgres@e2225346 )
that makes optimizations around disabled path nodes impacted pgvector
such that PostgreSQL would choose to perform an index scan when it
should have used a different scan (e.g. `SELECT count(*) FROM table`).
Per upstream guidance[1], the recommendation is to switch to using
`get_float8_infinity()`, which achieves the same behavior in backbranches,
and can be adapated to work with the new behavior introduced in PostgreSQL 18.

There are no references to anything that's in reloptions.h in the
header files. They need to include genam.h instead, which defines
IndexScanDesc.
