Enable the analyzer

Official CH changelog text
Enables the analyzer for CREATE/ALTER TABLE column default expression validation. #88087 (Max Justus Spransy).
Enables the analyzer to validate column default expressions in CREATE and ALTER TABLE statements.

Why it matters

This feature improves schema reliability by performing static analysis on default expressions when creating or altering table columns, preventing invalid or erroneous defaults from being applied.

How to use it

To use this feature, execute CREATE TABLE or ALTER TABLE statements with column default expressions as usual; the analyzer will automatically validate these expressions during query parsing.
