switch from github.com/lib/pq to github.com/jackc/pgx/v5HEAD20240905master

lib/pq is out of maintenance for some time now, so switch to the newer
more active library. Looks like it finally stabilized after a long time.

+// Package pgconn is a low-level PostgreSQL database driver.
+/*
+pgconn provides lower level access to a PostgreSQL connection than a database/sql or pgx connection. It operates at
+nearly the same level is the C library libpq.
+
+Establishing a Connection
+
+Use Connect to establish a connection. It accepts a connection string in URL or keyword/value format and will read the
+environment for libpq style environment variables.
+
+Executing a Query
+
+ExecParams and ExecPrepared execute a single query. They return readers that iterate over each row. The Read method
+reads all rows into memory.
+
+Executing Multiple Queries in a Single Round Trip
+
+Exec and ExecBatch can execute multiple queries in a single round trip. They return readers that iterate over each query
+result. The ReadAll method reads all query results into memory.
+
+Pipeline Mode
+
+Pipeline mode allows sending queries without having read the results of previously sent queries. It allows control of
+exactly how many and when network round trips occur.
+
+Context Support
+
+All potentially blocking operations take a context.Context. The default behavior when a context is canceled is for the
+method to immediately return. In most circumstances, this will also close the underlying connection. This behavior can
+be customized by using BuildContextWatcherHandler on the Config to create a ctxwatch.Handler with different behavior.
+This can be especially useful when queries that are frequently canceled and the overhead of creating new connections is
+a problem. DeadlineContextWatcherHandler and CancelRequestContextWatcherHandler can be used to introduce a delay before
+interrupting the query in such a way as to close the connection.
+
+The CancelRequest method may be used to request the PostgreSQL server cancel an in-progress query without forcing the
+client to abort.
