mjbshaw opened a new pull request, #2273:
URL: https://github.com/apache/datafusion-sqlparser-rs/pull/2273

   PostgreSQL 14 added 
[LOCK](https://www.postgresql.org/docs/current/sql-lock.html). This implements 
parsing support for that statement. Beyond the added tests, the following 
minimum reproducible example demonstrate's sqlparser's current failure to parse 
this statement:
   
   **Cargo.toml:**
   ```
   [package]
   name = "demo"
   version = "0.1.0"
   edition = "2024"
   
   [workspace]
   
   [dependencies]
   sqlparser_patched = { package = "sqlparser", path = 
"path/to/mjbshaw/fork/datafusion-sqlparser-rs" }
   sqlparser_published = { package = "sqlparser", version = "0.61.0" }
   ```
   
   **src/main.rs:**
   ```
   use sqlparser_patched::dialect::PostgreSqlDialect as 
PatchedPostgreSqlDialect;
   use sqlparser_patched::parser::Parser as PatchedParser;
   use sqlparser_published::dialect::PostgreSqlDialect as 
PublishedPostgreSqlDialect;
   use sqlparser_published::parser::Parser as PublishedParser;
   
   const SQL: &str = "LOCK TABLE public.widgets IN EXCLUSIVE MODE";
   
   fn main() {
       match PublishedParser::parse_sql(&PublishedPostgreSqlDialect {}, SQL) {
           Ok(statements) => panic!(
               "expected published sqlparser 0.61.0 to reject `{SQL}`, but it 
parsed: {statements:?}"
           ),
           Err(error) => {
               println!("published sqlparser 0.61.0 failed as expected: 
{error}");
           }
       }
   
       let statements = PatchedParser::parse_sql(&PatchedPostgreSqlDialect {}, 
SQL)
           .expect("patched sqlparser should parse PostgreSQL LOCK TABLE");
       assert_eq!(statements.len(), 1, "expected exactly one statement");
       println!("patched sqlparser parsed successfully: {}", statements[0]);
   }
   ```
   
   Then run with `cargo run`.
