Colummnar: mark custom scan path paralle_safe. (#4619) 
Enables an overall plan to be parallel (e.g. over a partition
hierarchy), even though an individual ColumnarScan is not
parallel-aware.

Columnar: always disable parallel paths. (#4617) 
Previously, if columnar.enable_custom_scan was false, parallel paths
could remain, leading to an unexpected error.

Also, ensure that cheapest_parameterized_paths is cleared if a custom
scan is used.

fix NaN cost estimate on empty columnar tables (#4593) 
Fixing a division by zero in the cost calculations for scanning a columnar table.

Due to how the columns in a columnar table are counted an empty table would result in a division by zero. Instead this patch keeps the column selection ratio on zero when this happens, resulting in an accurate cost of zero pages to scan a columnar table.

fixes #4589

fix parse error on pg11.8 for extension creation (#4582) 
In pg11.8 it seemingly tries to parse the full sql file creating the extension,
since we use syntax introduced in postgres 12 this fails.

This patch rewrites the statement not recognized by pg11.8 to be dynamically
executed from a string literal via `EXECUTE`.
