PRAGMA table_info strips type parameters from column declarations

Description

PRAGMA table_info strips parenthesized type parameters from column type declarations. SQLite preserves the complete type string exactly as written.

Reproducer

CREATE TABLE t(
  a VARCHAR(100),
  b CHAR(50),
  c DECIMAL(10,2),
  d NUMERIC(5,3),
  e FLOAT(24),
  f NVARCHAR(200)
);
PRAGMA table_info(t);
-- Turso type column: VARCHAR, CHAR, DECIMAL, NUMERIC, FLOAT, NVARCHAR
-- SQLite type column: VARCHAR(100), CHAR(50), DECIMAL(10,2), NUMERIC(5,3), FLOAT(24), NVARCHAR(200)

Per SQLite documentation: the "type" column reports the declared type of the column. The schema parser or column metadata storage strips the parenthesized parameters.
