Usage

Sources: GitHub repo, byteamagic docs Extension name: byteamagic The CSV package row is pg_byteamagic; the upstream extension name is byteamagic.

byteamagic uses libmagic on bytea values to identify the MIME type and the file type text inside PostgreSQL.

CREATE EXTENSION byteamagic;
SELECT byteamagic_mime(data);
SELECT byteamagic_text(data);

Functions

• byteamagic_mime(bytea) returns the MIME type as text and matches file --mime-type.
• byteamagic_text(bytea) returns a human-readable file type description and matches file.

Notes

• The extension needs PostgreSQL development headers and the libmagic development package.
• It is intended for databases that store files or blobs in bytea and need in-database type detection.
