sqlboiler generates int instead of int32 for PostgreSQL int4 type, causing type inconsistency

Problem Description

When using sqlboiler with PostgreSQL, int4 (integer) columns are generated as int type in Go structs instead of int32. This causes type inconsistency issues because:

1. PostgreSQL int4 is always 32-bit regardless of platform
2. Go int is platform-dependent (32-bit on 32-bit systems, 64-bit on 64-bit systems)
3. This leads to unnecessary type conversions and potential overflow issues on 32-bit systems

Current Behavior

PostgreSQL Schema:

CREATE TABLE img_category (
    id SERIAL PRIMARY KEY,  -- int4 type
    ......
);

Generated Go Code:

type ImgCategory struct {
    ID    int    `boil:"id" json:"id" toml:"id" yaml:"id"`
    ......
}

Expected Behavior

type ImgCategory struct {
    ID    int32  `boil:"id" json:"id" toml:"id" yaml:"id"`
   ......
}
