PL/pgSQL Deparser

Converts parsed PL/pgSQL function ASTs back into SQL source code. Part of the pgsql-parser ecosystem. v0.7.7 (stable, weekly releases). Key differentiator: round-tripping from AST to SQL with high fidelity, supporting PostgreSQL's PL/pgSQL dialect including complex control structures. Depends on libpg_query for parsing; you must parse first with pgsql-parser.
