So based on this, I've come up with:
"Node Type" TEXT, "Strategy" TEXT, "Operation" TEXT, "Startup Cost"
FLOAT, "Total Cost" FLOAT, "Plan Rows" FLOAT, "Plan Width" INTEGER, "Actual
StartupTime" FLOAT, "Actual Total Time" FLOAT, "Actual Rows" FLOAT, "Actual Loops"
FLOAT, "Parent Relationship" TEXT, "Sort Key" TEXT[], "Sort Method" TEXT[], "Sort Space
Used" BIGINT, "Sort Space Type" TEXT, "Join Type" TEXT, "Join Filter" TEXT,
"HashCond" TEXT, "Relation Name" NAME, "Alias" NAME, "Scan Direction"
TEXT, "Index Name" TEXT, "Index Cond" TEXT, "Recheck Cond" TEXT, "TID Cond"
TEXT, "Merge Cond" TEXT, "Subplan Name" TEXT, "Function Name" TEXT, "Function
Call" TEXT, "Filter" TEXT, "One-Time Filter" TEXT, "Command" TEXT,
"SharedHit Blocks" BIGINT, "Shared Read Blocks" BIGINT, "Shared Written Blocks" BIGINT, "Local Hit Blocks"
BIGINT, "Local Read Blocks" BIGINT, "Local Written Blocks" BIGINT, "Temp Read Blocks" BIGINT,
"TempWritten Blocks" BIGINT, "Output" TEXT[], "Hash Buckets" BIGINT, "Hash Batches"
BIGINT, "Original Hash Batches" BIGINT, "Peak Memory Usage" BIGINT, "Schema" TEXT, "CTE
Name" TEXT
Does that seem reasonable? Am I missing anything obvious?
Thanks,
David
