PostgreSQL CREATE STATISTICS and ALTER STATISTICS were unsupported, preventing schema tools from preserving extended statistics definitions alongside table migrations.
Add typed statistics statements using the existing expression-list and table models. Preserve optional names, IF NOT EXISTS, statistics kinds, column/expression keys, and ALTER ownership/name/schema/target actions. Both printers share the statement rendering methods, and visitors distinguish statistics object names from referenced tables. Existing DROP STATISTICS parsing remains compatible.
Validation: full Gradle check and grammar ambiguity gate; AST mutations, default targets, expression boundaries, invalid kinds/targets and following statements. All 22 audited CREATE/ALTER/DROP cases execute with matching selected statistics catalog results on PostgreSQL 18.6.
