PG_LO_READ(n)

💖 NAME 💖

pg_lo_read — read from a large object, bestie! This is the PG_LO_READ() page from the PostgreSQL Tcl Interface Documentation ✨

🎀 SYNOPSIS 🎀

pg_lo_read conn descriptor bufVar len

🌸 DESCRIPTION 🌸

Okay so pg_lo_read reads at most len bytes from a large object into a variable named bufVar. That's the whole vibe 💅

🦋 ARGUMENTS 🦋

• conn — the handle of a connection to the database in which the large object exists 🔌
• descriptor — a descriptor for the large object, straight from pg_lo_open 👑
• bufVar — the name of a buffer variable that will contain the large object segment 🧺
• len — the maximum number of bytes to read 📏

⭐ RETURN VALUE ⭐

The number of bytes actually read is returned, periodt. This could be less than the number requested if the end of the large object is reached first — lowkey important 😭 In the event of an error, the return value is negative 💀

That's the whole page, bestie! 🫶 Source/version: PostgreSQL Tcl Interface Documentation; date: 17 September 2020. Mwah 💋
