Overview ¶
Ported from postgres_deparse.c (libpg_query 18.0.0). Clause helpers: any_name, expression lists, target lists, from lists.
Ported from postgres_deparse.c (libpg_query 18.0.0). FROM/WHERE clauses, SELECT, function calls, window definitions, A_Expr.
Ported from postgres_deparse.c (libpg_query 18.0.0). Expressions: BoolExpr, CaseExpr, TypeCast/TypeName, constants; first DDL statements.
Ported from postgres_deparse.c (libpg_query 18.0.0). DDL: operator families, CREATE TABLE, constraints, indexes, DROP.
Ported from postgres_deparse.c (libpg_query 18.0.0). Grouping sets, DML statements (INSERT/UPDATE/DELETE/MERGE), ALTER TABLE, COPY.
Ported from postgres_deparse.c (libpg_query 18.0.0). DO, functions/procedures, roles, GRANT, transactions, views, policies.
Ported from postgres_deparse.c (libpg_query 18.0.0). ALTER statement long tail, publications/subscriptions, triggers, JSON aggregates.
Ported from postgres_deparse.c (libpg_query 18.0.0). JSON constructors, JSON_TABLE, value nodes, statement dispatch.
Package deparse ports libpg_query's postgres_deparse.c at the pinned 18.0.0, targeting the protobuf structs directly.
This file is the deparser state machinery: nesting levels, part groups and parts (postgres_deparse.c's DeparseState). The machinery exists for the optional pretty-print mode, which pg_query_go's API never enables, but it still shapes the plain output — parts are joined with single spaces, with no space after "(" or before a part starting with ")" or ";", and part groups fold their major keyword into their first part — so it is ported exactly rather than approximated. Comment placement is dropped entirely: comments can only arrive through deparse options the Go API does not expose.

Functions ¶
func Deparse ¶
func Deparse(tree *ast.ParseResult) (result string, err error)
Deparse is pg_query_deparse_protobuf: statements joined with "; ".
func DeparseWithEmpties ¶
DeparseWithEmpties is Deparse with the parser's present-but-empty string set: the C deparser distinguishes COMMENT/SECURITY LABEL ... IS ” (a non-NULL empty string) from IS NULL, which proto3 collapses. Only callers that re-parsed the input themselves (the summary truncation) can supply the set; trees received over the API deparse as the protobuf round-trip does upstream (both forms print IS NULL).
func QuoteIdentifier ¶
QuoteIdentifier exposes quoteIdentifier to the other internal packages that need ruleutils.c's quote_identifier (the summary walk renders table names with it).
