💖 App::Sqitch::Engine::pg — the PostgreSQL engine, bestie edition 💖

okay so this is App::Sqitch::Engine::pg, a page from the User Contributed Perl Documentation collection (yes, the whole thing is literally filed under App::S...ine::pg(3pm) in the index, love that for us 🎀). She's the PostgreSQL storage engine for Sqitch, and she is thriving.

that's it. that's the whole vibe. 🦋

🫶 DESCRIPTION 🫶

👑 INTERFACE 👑

🌟 Instance Methods 🌟

"initialized"

called like this:

$pg->initialize unless $pg->initialized;

returns true if the database has been initialized for Sqitch 💀 (she knows you, she remembers you), and false if it hasn't. like a little vibe check but for your registry schema.

"initialize"

called like this:

$pg->initialize;

Initializes a database for Sqitch by installing the Sqitch registry schema. basically setting up her whole little room. ✨

"psql"

Returns a list containing the psql client and options to be passed to it. Used internally when executing scripts — so no, you don't call this one at parties, she's backstage crew. 🧚 iykyk.
