Vacuum.

Description

Performs a VACUUM (garbage-collect and optionally analyze) on a table.

Usage

dbVacuum(
  conn,
  name,

  verbose = FALSE,
  analyze = TRUE,
  display = TRUE,
  exec = TRUE
)

Arguments

conn	A connection object.
name	A character string specifying a PostgreSQL table name.
full	Logical. Whether to perform a "full" vacuum, which can reclaim more space, but takes much longer and exclusively locks the table.
verbose	Logical. Whether to print a detailed vacuum activity report for each table.
analyze	Logical. Whether to update statistics used by the planner to determine the most efficient way to execute a query (default to TRUE).
display	Logical. Whether to display the query (defaults to TRUE).
