FAQPage Schema

How do I debug PostgreSQL syntax parsing issues in gram.y?▼

To debug PostgreSQL syntax parsing in gram.y, reference the grammar definitions alongside scan.l and keywords.c to trace SQL construct parsing rules, identify grammar conflicts, and validate DDL generation workflows for pgschema.

What is the best way to validate DDL generation across PostgreSQL versions?▼

Validating DDL generation across PostgreSQL versions requires consulting parser components like gram.y and keywords.c to ensure SQL constructs and grammar rules align with specific version definitions, enabling accurate parsing and valid DDL output.

How does the PostgreSQL parser handle complex SQL constructs in scan.l?▼

The PostgreSQL parser handles complex SQL constructs in scan.l by defining lexical tokenization rules that feed into gram.y grammar definitions, ensuring accurate parsing of SQL statements and supporting correct DDL generation in pgschema.

Can I use PostgreSQL grammar references to implement SQL parsing rules?▼

Yes, PostgreSQL grammar references like gram.y, scan.l, and keywords.c provide the foundational parser definitions needed to implement, audit, and map SQL parsing rules accurately for DDL generation workflows in pgschema.

Why does my PostgreSQL DDL generation fail on certain SQL syntax?▼

PostgreSQL DDL generation fails on certain SQL syntax when parser definitions in gram.y and scan.l are not fully consulted, causing mismatches between SQL constructs and grammar rules across different PostgreSQL versions.

When do I need to consult keywords.c for PostgreSQL syntax parsing?▼

You need to consult keywords.c for PostgreSQL syntax parsing when auditing keyword classifications, validating reserved word handling, or ensuring SQL constructs parse correctly before generating DDL in pgschema across PostgreSQL versions.
