More Parser Validation + CI Hardening

v2.54.0 - 2026-05-24

Added

• lexer: add parsing and erroring for num trailing suffix (#1159)

  error[syntax-error]: trailing junk after numeric literal
    ╭▸ stdin:1:11
    │
  1 │ SELECT 0x0y;
    ╰╴          ━
  

• parser: warn about empty / invalid params & empty quoted idents (#1164)

  error[syntax-error]: empty delimited identifier
    ╭▸ stdin:1:8
    │
  1 │ select "", $, $2147483648
    ╰╴       ━━
  error[syntax-error]: missing parameter number
    ╭▸ stdin:1:12
    │
  1 │ select "", $, $2147483648
    ╰╴           ━
  error[syntax-error]: parameter number too large
    ╭▸ stdin:1:15
    │
  1 │ select "", $, $2147483648
    ╰╴              ━━━━━━━━━━━
  

• parser: warn about invalid octal/hex/binary digits (#1163)

  error[syntax-error]: invalid digit for a base 2 literal
    ╭▸ stdin:1:12
    │
  1 │ select 0b104, 0o7719, 0xg
    ╰╴           ━
  error[syntax-error]: invalid digit for a base 8 literal
    ╭▸ stdin:1:20
    │
  1 │ select 0b104, 0o7719, 0xg
    ╰╴                   ━
  error[syntax-error]: trailing junk after numeric literal
    ╭▸ stdin:1:25
    │
  1 │ select 0b104, 0o7719, 0xg
    ╰╴                        ━
  

• parser: improve error reporting for malformed literals (#1162)

  error[syntax-error]: trailing junk after positional parameter
    ╭▸ stdin:1:10
    │
  1 │ SELECT $1a;
    ╰╴         ━
  

  instead of

  error[syntax-error]: trailing junk after positional parameter
    ╭▸ stdin:1:10
    │
  1 │ SELECT $1a;
    ╰╴       ━━━
  

• parser: improve lexing numbers (#1161)

  select .4;

  now produces:

  NUMERIC_NUMBER@7..9 ".4"
  

  instead of:

  INT_NUMBER@7..9 ".4"
  

• ide: goto def for t.c%type (#1161)

  create table t(a int, b text);
  --           ^ dest
  create function f(x t.a%type) returns s.t.b%type
  --                  ^ source
    as $$ select 'hello'::text $$ language sql;

• ide: find refs for types like bit (#1153)

  create type pg_catalog.bit;
  --                     ^^^ source
  
  create function pg_catalog.bit(bigint, integer) returns bit
  --                                                      ^^^ ref
    language internal;

• ide: add hover for string literals (#1155)

  Now we decode the escape sequences for string literals on hover and show the
  value up to the first new line.

• ide: improve numeric literal type inference (#1156)

  select 2147483647; -- type: integer
  select 2147483648; -- type: bigint
  select 100000000000000000000000; -- type: numeric

• fmt: literals & binary operators (#1169)

  Format binary operators and literals.

  -- before
  select TRUE  and  FALSE;
  select X'AF';
  
  -- after
  select true and false;
  select
    x'AF';

• fmt: unquote column aliases when possible (#1168)

  -- before
  select 1 as "foo";
  
  -- after
  select 1 as foo;
