Valid PostgreSQL TRUNCATE forms such as
TRUNCATE ONLY (t), child * RESTART IDENTITY RESTRICTwere not supported. The existing visitors also processed only one table in a multiple-table TRUNCATE.Share relation targets with LOCK TABLE, representing per-target ONLY, parenthesized ONLY, and descendant
*scope. Add structured RESTART/CONTINUE IDENTITY and CASCADE/RESTRICT options, use one rendering path, and visit/validate every target. Preserve the legacy getTable accessor's last-target behavior and provide a mutable getTables projection onto the same target objects.Tests cover target/option combinations, legacy and structured mutations, all-table traversal, shared LOCK targets, malformed clauses, and statement boundaries. Executed the relevant corpus and nine additional inheritance/identity combinations on PostgreSQL 18.6; original and rendered SQL produce matching table, row-count and sequence state.
Syntax references: TRUNCATE, LOCK.
Validation: focused tests, JavaCC ambiguity checks, Checkstyle and Spotless on this independent branch. The combined implementation also passes the full Gradle check and Maven verify; the 1,304-input prior regression corpus has no previously successful input regressions.
